This also means that - * it is rather complex and can take some time to fully master. - * - * \section mainloop_sec Main Loop Abstraction - * - * The API is based around an asynchronous event loop, or main loop, - * abstraction. This abstraction contains three basic elements: - * - * \li Deferred events - Events that will trigger as soon as possible. Note - * that some implementations may block all other events - * when a deferred event is active. - * \li I/O events - Events that trigger on file descriptor activities. - * \li Times events - Events that trigger after a fixed ammount of time. - * - * The abstraction is represented as a number of function pointers in the - * pa_mainloop_api structure. - * - * To actually be able to use these functions, an implementation needs to - * be coupled to the abstraction. There are three of these shipped with - * polypaudio, but any other can be used with a minimal ammount of work, - * provided it supports the three basic events listed above. - * - * The implementations shipped with polypaudio are: - * - * \li \subpage mainloop - A minimal but fast implementation based on poll(). - * \li \subpage threaded_mainloop - A special version of the previous - * implementation where all of Polypaudio's - * internal handling runs in a separate - * thread. - * \li \subpage glib-mainloop - A wrapper around GLIB's main loop. Available - * for both GLIB 1.2 and GLIB 2.x. - * - * UNIX signals may be hooked to a main loop using the functions from - * \ref mainloop-signal.h. These rely only on the main loop abstraction - * and can therefore be used with any of the implementations. - * - * \section refcnt_sec Reference Counting - * - * Almost all objects in polypaudio are reference counted. What that means - * is that you rarely malloc() or free() any objects. Instead you increase - * and decrease their reference counts. Whenever an object's reference - * count reaches zero, that object gets destroy and any resources it uses - * get freed. - * - * The benefit of this design is that an application need not worry about - * whether or not it needs to keep an object around in case the library is - * using it internally. If it is, then it has made sure it has its own - * reference to it. - * - * Whenever the library creates an object, it will have an initial - * reference count of one. Most of the time, this single reference will be - * sufficient for the application, so all required reference count - * interaction will be a single call to the objects unref function. - * - * \section context_sec Context - * - * A context is the basic object for a connection to a polypaudio server. - * It multiplexes commands, data streams and events through a single - * channel. - * - * There is no need for more than one context per application, unless - * connections to multiple servers are needed. - * - * \subsection ops_subsec Operations - * - * All operations on the context are performed asynchronously. I.e. the - * client will not wait for the server to complete the request. To keep - * track of all these in-flight operations, the application is given a - * pa_operation object for each asynchronous operation. - * - * There are only two actions (besides reference counting) that can be - * performed on a pa_operation: querying its state with - * pa_operation_get_state() and aborting it with pa_operation_cancel(). - * - * A pa_operation object is reference counted, so an application must - * make sure to unreference it, even if it has no intention of using it. - * - * \subsection conn_subsec Connecting - * - * A context must be connected to a server before any operation can be - * issued. Calling pa_context_connect() will initiate the connection - * procedure. Unlike most asynchronous operations, connecting does not - * result in a pa_operation object. Instead, the application should - * register a callback using pa_context_set_state_callback(). - * - * \subsection disc_subsec Disconnecting - * - * When the sound support is no longer needed, the connection needs to be - * closed using pa_context_disconnect(). This is an immediate function that - * works synchronously. - * - * Since the context object has references to other objects it must be - * disconnected after use or there is a high risk of memory leaks. If the - * connection has terminated by itself, then there is no need to explicitly - * disconnect the context using pa_context_disconnect(). - * - * \section Functions - * - * The sound server's functionality can be divided into a number of - * subsections: - * - * \li \subpage streams - * \li \subpage scache - * \li \subpage introspect - * \li \subpage subscribe - */ - -/** \file - * Connection contexts for asynchrononous communication with a - * server.

For this, Polypaudio has the introspection API. It can list sinks, - * sources, samples and other aspects of the server. It can also modify the - * attributes of the server that will affect operations on a global level, - * and not just the application's context. - * - * \section query_sec Querying - * - * All querying is done through callbacks. This design is necessary to - * maintain an asynchronous design. The client will request the information - * and some time later, the server will respond with the desired data. - * - * Some objects can have multiple entries at the server. When requesting all - * of these at once, the callback will be called multiple times, once for - * each object. When the list has been exhausted, the callback will be called - * without an information structure and the eol parameter set to a non-zero - * value. - * - * Note that even if a single object is requested, and not the entire list, - * the terminating call will still be made. - * - * If an error occurs, the callback will be called without and information - * structure and eol set to zero. - * - * Data members in the information structures are only valid during the - * duration of the callback. If they are required after the callback is - * finished, a deep copy must be performed. - * - * \subsection server_subsec Server Information - * - * The server can be queried about its name, the environment it's running on - * and the currently active global defaults. Calling - * pa_context_get_server_info() will get access to a pa_server_info structure - * containing all of these. - * - * \subsection memstat_subsec Memory Usage - * - * Statistics about memory usage can be fetched using pa_context_stat(), - * giving a pa_stat_info structure. - * - * \subsection sinksrc_subsec Sinks and Sources - * - * The server can have an arbitrary number of sinks and sources. Each sink - * and source have both an index and a name associated with it. As such - * there are three ways to get access to them: - * - * \li By index - pa_context_get_sink_info_by_index() / - * pa_context_get_source_info_by_index() - * \li By name - pa_context_get_sink_info_by_name() / - * pa_context_get_source_info_by_name() - * \li All - pa_context_get_sink_info_list() / - * pa_context_get_source_info_list() - * - * All three method use the same callback and will provide a pa_sink_info or - * pa_source_info structure. - * - * \subsection siso_subsec Sink Inputs and Source Outputs - * - * Sink inputs and source outputs are the representations of the client ends - * of streams inside the server. I.e. they connect a client stream to one of - * the global sinks or sources. - * - * Sink inputs and source outputs only have an index to identify them. As - * such, there are only two ways to get information about them: - * - * \li By index - pa_context_get_sink_input_info() / - * pa_context_get_source_output_info() - * \li All - pa_context_get_sink_input_info_list() / - * pa_context_get_source_output_info_list() - * - * The structure returned is the pa_sink_input_info or pa_source_output_info - * structure. - * - * \subsection samples_subsec Samples - * - * The list of cached samples can be retrieved from the server. Three methods - * exist for querying the sample cache list: - * - * \li By index - pa_context_get_sample_info_by_index() - * \li By name - pa_context_get_sample_info_by_name() - * \li All - pa_context_get_sample_info_list() - * - * Note that this only retrieves information about the sample, not the sample - * data itself. - * - * \subsection module_subsec Driver Modules - * - * Polypaudio driver modules are identified by index and are retrieved using either - * pa_context_get_module_info() or pa_context_get_module_info_list(). The - * information structure is called pa_module_info. - * - * \subsection autoload_subsec Autoload Entries - * - * Modules can be autoloaded as a result of a client requesting a certain - * sink or source. This mapping between sink/source names and modules can be - * queried from the server: - * - * \li By index - pa_context_get_autoload_info_by_index() - * \li By sink/source name - pa_context_get_autoload_info_by_name() - * \li All - pa_context_get_autoload_info_list() - * - * \subsection client_subsec Clients - * - * Polypaudio clients are also identified by index and are retrieved using - * either pa_context_get_client_info() or pa_context_get_client_info_list(). - * The information structure is called pa_client_info. - * - * \section ctrl_sec Control - * - * Some parts of the server are only possible to read, but most can also be - * modified in different ways. Note that these changes will affect all - * connected clients and not just the one issuing the request. - * - * \subsection sinksrc_subsec Sinks and Sources - * - * The most common change one would want to do to sinks and sources is to - * modify the volume of the audio. Identical to how sinks and sources can - * be queried, there are two ways of identifying them: - * - * \li By index - pa_context_set_sink_volume_by_index() / - * pa_context_set_source_volume_by_index() - * \li By name - pa_context_set_sink_volume_by_name() / - * pa_context_set_source_volume_by_name() - * - * It is also possible to mute a sink or source: - * - * \li By index - pa_context_set_sink_mute_by_index() / - * pa_context_set_source_mute_by_index() - * \li By name - pa_context_set_sink_mute_by_name() / - * pa_context_set_source_mute_by_name() - * - * \subsection siso_subsec Sink Inputs and Source Outputs - * - * If an application desires to modify the volume of just a single stream - * (commonly one of its own streams), this can be done by setting the volume - * of its associated sink input, using pa_context_set_sink_input_volume(). - * - * There is no support for modifying the volume of source outputs. - * - * It is also possible to remove sink inputs and source outputs, terminating - * the streams associated with them: - * - * \li Sink input - pa_context_kill_sink_input() - * \li Source output - pa_context_kill_source_output() - * - * \subsection module_subsec Modules - * - * Server modules can be remotely loaded and unloaded using - * pa_context_load_module() and pa_context_unload_module(). - * - * \subsection autoload_subsec Autoload Entries - * - * New module autoloading rules can be added, and existing can be removed - * using pa_context_add_autoload() and pa_context_remove_autoload_by_index() - * / pa_context_remove_autoload_by_name(). - * - * \subsection client_subsec Clients - * - * The only operation supported on clients, is the possibility of kicking - * them off the server using pa_context_kill_client(). - */ - -/** \file - * - * Routines for daemon introspection. - */ - -PA_C_DECL_BEGIN - -/** Stores information about sinks */ -typedef struct pa_sink_info { - const char *name;

It is, however, very simple to use and - * quite sufficent for many programs. - * - * \section conn_sec Connecting - * - * The first step before using the sound system is to connect to the - * server. This is normally done this way: - * - * \code - * pa_simple *s; - * pa_sample_spec ss; - * - * ss.format = PA_SAMPLE_S16_NE; - * ss.channels = 2; - * ss.rate = 44100; - * - * s = pa_simple_new(NULL, // Use the default server. - * "Fooapp", // Our application's name. - * PA_STREAM_PLAYBACK, - * NULL, // Use the default device. - * "Music", // Description of our stream. - * &ss, // Our sample format. - * NULL, // Use default channel map - * NULL, // Use default buffering attributes. - * NULL, // Ignore error code. - * ); - * \endcode - * - * At this point a connected object is returned, or NULL if there was a - * problem connecting. - * - * \section transfer_sec Transferring data - * - * Once the connection is established to the server, data can start flowing. - * Using the connection is very similar to the normal read() and write() - * system calls. The main difference is that they're call pa_simple_read() - * and pa_simple_write(). Note that these operations always block. - * - * \section ctrl_sec Buffer control - * - * If a playback stream is used then a few other operations are available: - * - * \li pa_simple_drain() - Will wait for all sent data to finish playing. - * \li pa_simple_flush() - Will throw away all data currently in buffers. - * \li pa_simple_get_playback_latency() - Will return the total latency of - * the playback pipeline. - * - * \section cleanup_sec Cleanup - * - * Once playback or capture is complete, the connection should be closed - * and resources freed.

Data is - * routed, converted and mixed from several sources before it is passed along - * to a final output. Currently, there are three forms of audio streams: - * - * \li Playback streams - Data flows from the client to the server. - * \li Record streams - Data flows from the server to the client. - * \li Upload streams - Similar to playback streams, but the data is stored in - * the sample cache. See \ref scache for more information - * about controlling the sample cache. - * - * \section create_sec Creating - * - * To access a stream, a pa_stream object must be created using - * pa_stream_new(). At this point the audio sample format and mapping of - * channels must be specified. See \ref sample and \ref channelmap for more - * information about those structures. - * - * This first step will only create a client-side object, representing the - * stream. To use the stream, a server-side object must be created and - * associated with the local object. Depending on which type of stream is - * desired, a different function is needed: - * - * \li Playback stream - pa_stream_connect_playback() - * \li Record stream - pa_stream_connect_record() - * \li Upload stream - pa_stream_connect_upload() (see \ref scache) - * - * Similar to how connections are done in contexts, connecting a stream will - * not generate a pa_operation object. Also like contexts, the application - * should register a state change callback, using - * pa_stream_set_state_callback(), and wait for the stream to enter an active - * state. - * - * \subsection bufattr_subsec Buffer Attributes - * - * Playback and record streams always have a server side buffer as - * part of the data flow. The size of this buffer strikes a - * compromise between low latency and sensitivity for buffer - * overflows/underruns. - * - * The buffer metrics may be controlled by the application. They are - * described with a pa_buffer_attr structure which contains a number - * of fields: - * - * \li maxlength - The absolute maximum number of bytes that can be stored in - * the buffer. If this value is exceeded then data will be - * lost. - * \li tlength - The target length of a playback buffer. The server will only - * send requests for more data as long as the buffer has less - * than this number of bytes of data. - * \li prebuf - Number of bytes that need to be in the buffer before - * playback will commence. Start of playback can be forced using - * pa_stream_trigger() even though the prebuffer size hasn't been - * reached. If a buffer underrun occurs, this prebuffering will be - * again enabled. If the playback shall never stop in case of a buffer - * underrun, this value should be set to 0. In that case the read - * index of the output buffer overtakes the write index, and hence the - * fill level of the buffer is negative. - * \li minreq - Minimum free number of the bytes in the playback buffer before - * the server will request more data. - * \li fragsize - Maximum number of bytes that the server will push in one - * chunk for record streams. - * - * The server side playback buffers are indexed by a write and a read - * index. The application writes to the write index and the sound - * device reads from the read index. The read index is increased - * monotonically, while the write index may be freely controlled by - * the application. Substracting the read index from the write index - * will give you the current fill level of the buffer. The read/write - * indexes are 64bit values and measured in bytes, they will never - * wrap. The current read/write index may be queried using - * pa_stream_get_timing_info() (see below for more information). In - * case of a buffer underrun the read index is equal or larger than - * the write index. Unless the prebuf value is 0, Polypaudio will - * temporarily pause playback in such a case, and wait until the - * buffer is filled up to prebuf bytes again. If prebuf is 0, the - * read index may be larger than the write index, in which case - * silence is played. If the application writes data to indexes lower - * than the read index, the data is immediately lost. - * - * \section transfer_sec Transferring Data - * - * Once the stream is up, data can start flowing between the client and the - * server. Two different access models can be used to transfer the data: - * - * \li Asynchronous - The application register a callback using - * pa_stream_set_write_callback() and - * pa_stream_set_read_callback() to receive notifications - * that data can either be written or read. - * \li Polled - Query the library for available data/space using - * pa_stream_writable_size() and pa_stream_readable_size() and - * transfer data as needed. The sizes are stored locally, in the - * client end, so there is no delay when reading them. - * - * It is also possible to mix the two models freely. - * - * Once there is data/space available, it can be transferred using either - * pa_stream_write() for playback, or pa_stream_peek() / pa_stream_drop() for - * record. Make sure you do not overflow the playback buffers as data will be - * dropped. - * - * \section bufctl_sec Buffer Control - * - * The transfer buffers can be controlled through a number of operations: - * - * \li pa_stream_cork() - Start or stop the playback or recording. - * \li pa_stream_trigger() - Start playback immediatly and do not wait for - * the buffer to fill up to the set trigger level. - * \li pa_stream_prebuf() - Reenable the playback trigger level. - * \li pa_stream_drain() - Wait for the playback buffer to go empty. Will - * return a pa_operation object that will indicate when - * the buffer is completely drained. - * \li pa_stream_flush() - Drop all data from the playback buffer and do not - * wait for it to finish playing. - * - * \section seek_modes Seeking in the Playback Buffer - * - * A client application may freely seek in the playback buffer. To - * accomplish that the pa_stream_write() function takes a seek mode - * and an offset argument. The seek mode is one of: - * - * \li PA_SEEK_RELATIVE - seek relative to the current write index - * \li PA_SEEK_ABSOLUTE - seek relative to the beginning of the playback buffer, (i.e. the first that was ever played in the stream) - * \li PA_SEEK_RELATIVE_ON_READ - seek relative to the current read index. Use this to write data to the output buffer that should be played as soon as possible - * \li PA_SEEK_RELATIVE_END - seek relative to the last byte ever written. - * - * If an application just wants to append some data to the output - * buffer, PA_SEEK_RELATIVE and an offset of 0 should be used. - * - * After a call to pa_stream_write() the write index will be left at - * the position right after the last byte of the written data. - * - * \section latency_sec Latency - * - * A major problem with networked audio is the increased latency caused by - * the network. To remedy this, Polypaudio supports an advanced system of - * monitoring the current latency. - * - * To get the raw data needed to calculate latencies, call - * pa_stream_get_timing_info(). This will give you a pa_timing_info - * structure that contains everything that is known about the server - * side buffer transport delays and the backend active in the - * server. (Besides other things it contains the write and read index - * values mentioned above.) - * - * This structure is updated every time a - * pa_stream_update_timing_info() operation is executed. (i.e. before - * the first call to this function the timing information structure is - * not available!) Since it is a lot of work to keep this structure - * up-to-date manually, Polypaudio can do that automatically for you: - * if PA_STREAM_AUTO_TIMING_UPDATE is passed when connecting the - * stream Polypaudio will automatically update the structure every - * 100ms and every time a function is called that might invalidate the - * previously known timing data (such as pa_stream_write() or - * pa_stream_flush()). Please note however, that there always is a - * short time window when the data in the timing information structure - * is out-of-date. Polypaudio tries to mark these situations by - * setting the write_index_corrupt and read_index_corrupt fields - * accordingly. - * - * The raw timing data in the pa_timing_info structure is usually hard - * to deal with. Therefore a more simplistic interface is available: - * you can call pa_stream_get_time() or pa_stream_get_latency(). The - * former will return the current playback time of the hardware since - * the stream has been started. The latter returns the time a sample - * that you write now takes to be played by the hardware. These two - * functions base their calculations on the same data that is returned - * by pa_stream_get_timing_info(). Hence the same rules for keeping - * the timing data up-to-date apply here. In case the write or read - * index is corrupted, these two functions will fail with - * PA_ERR_NODATA set. - * - * Since updating the timing info structure usually requires a full - * network round trip and some applications monitor the timing very - * often Polypaudio offers a timing interpolation system. If - * PA_STREAM_INTERPOLATE_TIMING is passed when connecting the stream, - * pa_stream_get_time() and pa_stream_get_latency() will try to - * interpolate the current playback time/latency by estimating the - * number of samples that have been played back by the hardware since - * the last regular timing update. It is espcially useful to combine - * this option with PA_STREAM_AUTO_TIMING_UPDATE, which will enable - * you to monitor the current playback time/latency very precisely and - * very frequently without requiring a network round trip every time. - * - * \section flow_sec Overflow and underflow - * - * Even with the best precautions, buffers will sometime over - or - * underflow. To handle this gracefully, the application can be - * notified when this happens. Callbacks are registered using - * pa_stream_set_overflow_callback() and - * pa_stream_set_underflow_callback(). - * - * \section sync_streams Sychronizing Multiple Playback Streams - * - * Polypaudio allows applications to fully synchronize multiple - * playback streams that are connected to the same output device. That - * means the streams will always be played back sample-by-sample - * synchronously.

For the basic design, see - * its documentation. - * - * The added feature in the threaded main loop is that it spawns a new thread - * that runs the real main loop. This allows a synchronous application to use - * the asynchronous API without risking to stall the Polypaudio library. - * - * \section creat_sec Creation - * - * A pa_threaded_mainloop object is created using pa_threaded_mainloop_new(). - * This will only allocate the required structures though, so to use it the - * thread must also be started. This is done through - * pa_threaded_mainloop_start(), after which you can start using the main loop. - * - * \section destr_sec Destruction - * - * When the Polypaudio connection has been terminated, the thread must be - * stopped and the resources freed. Stopping the thread is done using - * pa_threaded_mainloop_stop(), which must be called without the lock (see - * below) held. When that function returns, the thread is stopped and the - * pa_threaded_mainloop object can be freed using pa_threaded_mainloop_free(). - * - * \section lock_sec Locking - * - * Since the Polypaudio API doesn't allow concurrent accesses to objects, - * a locking scheme must be used to guarantee safe usage. The threaded main - * loop API provides such a scheme through the functions - * pa_threaded_mainloop_lock() and pa_threaded_mainloop_unlock(). - * - * The lock is recursive, so it's safe to use it multiple times from the same - * thread. Just make sure you call pa_threaded_mainloop_unlock() the same - * number of times you called pa_threaded_mainloop_lock(). - * - * The lock needs to be held whenever you call any Polypaudio function that - * uses an object associated with this main loop. Make sure you do not hold - * on to the lock more than necessary though, as the threaded main loop stops - * while the lock is held. - * - * Example: - * - * \code - * void my_check_stream_func(pa_threaded_mainloop *m, pa_stream *s) { - * pa_stream_state_t state; - * - * pa_threaded_mainloop_lock(m); - * - * state = pa_stream_get_state(s); - * - * pa_threaded_mainloop_unlock(m); - * - * if (state == PA_STREAM_READY) - * printf("Stream is ready!"); - * else - * printf("Stream is not ready!"); - * } - * \endcode - * - * \section cb_sec Callbacks - * - * Callbacks in Polypaudio are asynchronous, so they require extra care when - * using them together with a threaded main loop. - * - * The easiest way to turn the callback based operations into synchronous - * ones, is to simply wait for the callback to be called and continue from - * there. This is the approach chosen in Polypaudio's threaded API. - * - * \subsection basic_subsec Basic callbacks - * - * For the basic case, where all that is required is to wait for the callback - * to be invoked, the code should look something like this: - * - * Example: - * - * \code - * static void my_drain_callback(pa_stream*s, int success, void *userdata) { - * pa_threaded_mainloop *m; - * - * m = (pa_threaded_mainloop*)userdata; - * assert(m); - * - * pa_threaded_mainloop_signal(m, 0); - * } - * - * void my_drain_stream_func(pa_threaded_mainloop *m, pa_stream *s) { - * pa_operation *o; - * - * pa_threaded_mainloop_lock(m); - * - * o = pa_stream_drain(s, my_drain_callback, m); - * assert(o); - * - * while (pa_operation_get_state(o) != OPERATION_DONE) - * pa_threaded_mainloop_wait(m); - * - * pa_operation_unref(o); - * - * pa_threaded_mainloop_unlock(m); - * } - * \endcode - * - * The main function, my_drain_stream_func(), will wait for the callback to - * be called using pa_threaded_mainloop_wait(). - * - * If your application is multi-threaded, then this waiting must be done - * inside a while loop. The reason for this is that multiple threads might be - * using pa_threaded_mainloop_wait() at the same time. Each thread must - * therefore verify that it was its callback that was invoked. - * - * The callback, my_drain_callback(), indicates to the main function that it - * has been called using pa_threaded_mainloop_signal(). - * - * As you can see, both pa_threaded_mainloop_wait() may only be called with - * the lock held. The same thing is true for pa_threaded_mainloop_signal(), - * but as the lock is held before the callback is invoked, you do not have to - * deal with that. - * - * The functions will not dead lock because the wait function will release - * the lock before waiting and then regrab it once it has been signaled. - * For those of you familiar with threads, the behaviour is that of a - * condition variable. - * - * \subsection data_subsec Data callbacks - * - * For many callbacks, simply knowing that they have been called is - * insufficient. The callback also receives some data that is desired. To - * access this data safely, we must extend our example a bit: - * - * \code - * static int *drain_result; - * - * static void my_drain_callback(pa_stream*s, int success, void *userdata) { - * pa_threaded_mainloop *m; - * - * m = (pa_threaded_mainloop*)userdata; - * assert(m); - * - * drain_result = &success; - * - * pa_threaded_mainloop_signal(m, 1); - * } - * - * void my_drain_stream_func(pa_threaded_mainloop *m, pa_stream *s) { - * pa_operation *o; - * - * pa_threaded_mainloop_lock(m); - * - * o = pa_stream_drain(s, my_drain_callback, m); - * assert(o); - * - * while (pa_operation_get_state(o) != OPERATION_DONE) - * pa_threaded_mainloop_wait(m); - * - * pa_operation_unref(o); - * - * if (*drain_result) - * printf("Success!"); - * else - * printf("Bitter defeat..."); - * - * pa_threaded_mainloop_accept(m); - * - * pa_threaded_mainloop_unlock(m); - * } - * \endcode - * - * The example is a bit silly as it would probably have been easier to just - * copy the contents of success, but for larger data structures this can be - * wasteful. - * - * The difference here compared to the basic callback is the 1 sent to - * pa_threaded_mainloop_signal() and the call to - * pa_threaded_mainloop_accept(). What will happen is that - * pa_threaded_mainloop_signal() will signal the main function and then stop. - * The main function is then free to use the data in the callback until - * pa_threaded_mainloop_accept() is called, which will allow the callback - * to continue. - * - * Note that pa_threaded_mainloop_accept() must be called some time between - * exiting the while loop and unlocking the main loop! Failure to do so will - * result in a race condition. I.e. it is not ok to release the lock and - * regrab it before calling pa_threaded_mainloop_accept(). - * - * \subsection async_subsec Asynchronous callbacks - * - * Polypaudio also has callbacks that are completely asynchronous, meaning - * that they can be called at any time. The threading main loop API provides - * the locking mechanism to handle concurrent accesses, but nothing else. - * Applications will have to handle communication from the callback to the - * main program through some own system. - * - * The callbacks that are completely asynchronous are: - * - * \li State callbacks for contexts, streams, etc. - * \li Subscription notifications - */ - -/** \file - * - * A thread based event loop implementation based on pa_mainloop.

This also means that + * it is rather complex and can take some time to fully master. + * + * \section mainloop_sec Main Loop Abstraction + * + * The API is based around an asynchronous event loop, or main loop, + * abstraction. This abstraction contains three basic elements: + * + * \li Deferred events - Events that will trigger as soon as possible. Note + * that some implementations may block all other events + * when a deferred event is active. + * \li I/O events - Events that trigger on file descriptor activities. + * \li Times events - Events that trigger after a fixed ammount of time. + * + * The abstraction is represented as a number of function pointers in the + * pa_mainloop_api structure. + * + * To actually be able to use these functions, an implementation needs to + * be coupled to the abstraction. There are three of these shipped with + * pulseaudio, but any other can be used with a minimal ammount of work, + * provided it supports the three basic events listed above. + * + * The implementations shipped with pulseaudio are: + * + * \li \subpage mainloop - A minimal but fast implementation based on poll(). + * \li \subpage threaded_mainloop - A special version of the previous + * implementation where all of Polypaudio's + * internal handling runs in a separate + * thread. + * \li \subpage glib-mainloop - A wrapper around GLIB's main loop. Available + * for both GLIB 1.2 and GLIB 2.x. + * + * UNIX signals may be hooked to a main loop using the functions from + * \ref mainloop-signal.h. These rely only on the main loop abstraction + * and can therefore be used with any of the implementations. + * + * \section refcnt_sec Reference Counting + * + * Almost all objects in pulseaudio are reference counted. What that means + * is that you rarely malloc() or free() any objects. Instead you increase + * and decrease their reference counts. Whenever an object's reference + * count reaches zero, that object gets destroy and any resources it uses + * get freed. + * + * The benefit of this design is that an application need not worry about + * whether or not it needs to keep an object around in case the library is + * using it internally. If it is, then it has made sure it has its own + * reference to it. + * + * Whenever the library creates an object, it will have an initial + * reference count of one. Most of the time, this single reference will be + * sufficient for the application, so all required reference count + * interaction will be a single call to the objects unref function. + * + * \section context_sec Context + * + * A context is the basic object for a connection to a pulseaudio server. + * It multiplexes commands, data streams and events through a single + * channel. + * + * There is no need for more than one context per application, unless + * connections to multiple servers are needed. + * + * \subsection ops_subsec Operations + * + * All operations on the context are performed asynchronously. I.e. the + * client will not wait for the server to complete the request. To keep + * track of all these in-flight operations, the application is given a + * pa_operation object for each asynchronous operation. + * + * There are only two actions (besides reference counting) that can be + * performed on a pa_operation: querying its state with + * pa_operation_get_state() and aborting it with pa_operation_cancel(). + * + * A pa_operation object is reference counted, so an application must + * make sure to unreference it, even if it has no intention of using it. + * + * \subsection conn_subsec Connecting + * + * A context must be connected to a server before any operation can be + * issued. Calling pa_context_connect() will initiate the connection + * procedure. Unlike most asynchronous operations, connecting does not + * result in a pa_operation object. Instead, the application should + * register a callback using pa_context_set_state_callback(). + * + * \subsection disc_subsec Disconnecting + * + * When the sound support is no longer needed, the connection needs to be + * closed using pa_context_disconnect(). This is an immediate function that + * works synchronously. + * + * Since the context object has references to other objects it must be + * disconnected after use or there is a high risk of memory leaks. If the + * connection has terminated by itself, then there is no need to explicitly + * disconnect the context using pa_context_disconnect(). + * + * \section Functions + * + * The sound server's functionality can be divided into a number of + * subsections: + * + * \li \subpage streams + * \li \subpage scache + * \li \subpage introspect + * \li \subpage subscribe + */ + +/** \file + * Connection contexts for asynchrononous communication with a + * server.

For this, Polypaudio has the introspection API. It can list sinks, + * sources, samples and other aspects of the server. It can also modify the + * attributes of the server that will affect operations on a global level, + * and not just the application's context. + * + * \section query_sec Querying + * + * All querying is done through callbacks. This design is necessary to + * maintain an asynchronous design. The client will request the information + * and some time later, the server will respond with the desired data. + * + * Some objects can have multiple entries at the server. When requesting all + * of these at once, the callback will be called multiple times, once for + * each object. When the list has been exhausted, the callback will be called + * without an information structure and the eol parameter set to a non-zero + * value. + * + * Note that even if a single object is requested, and not the entire list, + * the terminating call will still be made. + * + * If an error occurs, the callback will be called without and information + * structure and eol set to zero. + * + * Data members in the information structures are only valid during the + * duration of the callback. If they are required after the callback is + * finished, a deep copy must be performed. + * + * \subsection server_subsec Server Information + * + * The server can be queried about its name, the environment it's running on + * and the currently active global defaults. Calling + * pa_context_get_server_info() will get access to a pa_server_info structure + * containing all of these. + * + * \subsection memstat_subsec Memory Usage + * + * Statistics about memory usage can be fetched using pa_context_stat(), + * giving a pa_stat_info structure. + * + * \subsection sinksrc_subsec Sinks and Sources + * + * The server can have an arbitrary number of sinks and sources. Each sink + * and source have both an index and a name associated with it. As such + * there are three ways to get access to them: + * + * \li By index - pa_context_get_sink_info_by_index() / + * pa_context_get_source_info_by_index() + * \li By name - pa_context_get_sink_info_by_name() / + * pa_context_get_source_info_by_name() + * \li All - pa_context_get_sink_info_list() / + * pa_context_get_source_info_list() + * + * All three method use the same callback and will provide a pa_sink_info or + * pa_source_info structure. + * + * \subsection siso_subsec Sink Inputs and Source Outputs + * + * Sink inputs and source outputs are the representations of the client ends + * of streams inside the server. I.e. they connect a client stream to one of + * the global sinks or sources. + * + * Sink inputs and source outputs only have an index to identify them. As + * such, there are only two ways to get information about them: + * + * \li By index - pa_context_get_sink_input_info() / + * pa_context_get_source_output_info() + * \li All - pa_context_get_sink_input_info_list() / + * pa_context_get_source_output_info_list() + * + * The structure returned is the pa_sink_input_info or pa_source_output_info + * structure. + * + * \subsection samples_subsec Samples + * + * The list of cached samples can be retrieved from the server. Three methods + * exist for querying the sample cache list: + * + * \li By index - pa_context_get_sample_info_by_index() + * \li By name - pa_context_get_sample_info_by_name() + * \li All - pa_context_get_sample_info_list() + * + * Note that this only retrieves information about the sample, not the sample + * data itself. + * + * \subsection module_subsec Driver Modules + * + * Polypaudio driver modules are identified by index and are retrieved using either + * pa_context_get_module_info() or pa_context_get_module_info_list(). The + * information structure is called pa_module_info. + * + * \subsection autoload_subsec Autoload Entries + * + * Modules can be autoloaded as a result of a client requesting a certain + * sink or source. This mapping between sink/source names and modules can be + * queried from the server: + * + * \li By index - pa_context_get_autoload_info_by_index() + * \li By sink/source name - pa_context_get_autoload_info_by_name() + * \li All - pa_context_get_autoload_info_list() + * + * \subsection client_subsec Clients + * + * Polypaudio clients are also identified by index and are retrieved using + * either pa_context_get_client_info() or pa_context_get_client_info_list(). + * The information structure is called pa_client_info. + * + * \section ctrl_sec Control + * + * Some parts of the server are only possible to read, but most can also be + * modified in different ways. Note that these changes will affect all + * connected clients and not just the one issuing the request. + * + * \subsection sinksrc_subsec Sinks and Sources + * + * The most common change one would want to do to sinks and sources is to + * modify the volume of the audio. Identical to how sinks and sources can + * be queried, there are two ways of identifying them: + * + * \li By index - pa_context_set_sink_volume_by_index() / + * pa_context_set_source_volume_by_index() + * \li By name - pa_context_set_sink_volume_by_name() / + * pa_context_set_source_volume_by_name() + * + * It is also possible to mute a sink or source: + * + * \li By index - pa_context_set_sink_mute_by_index() / + * pa_context_set_source_mute_by_index() + * \li By name - pa_context_set_sink_mute_by_name() / + * pa_context_set_source_mute_by_name() + * + * \subsection siso_subsec Sink Inputs and Source Outputs + * + * If an application desires to modify the volume of just a single stream + * (commonly one of its own streams), this can be done by setting the volume + * of its associated sink input, using pa_context_set_sink_input_volume(). + * + * There is no support for modifying the volume of source outputs. + * + * It is also possible to remove sink inputs and source outputs, terminating + * the streams associated with them: + * + * \li Sink input - pa_context_kill_sink_input() + * \li Source output - pa_context_kill_source_output() + * + * \subsection module_subsec Modules + * + * Server modules can be remotely loaded and unloaded using + * pa_context_load_module() and pa_context_unload_module(). + * + * \subsection autoload_subsec Autoload Entries + * + * New module autoloading rules can be added, and existing can be removed + * using pa_context_add_autoload() and pa_context_remove_autoload_by_index() + * / pa_context_remove_autoload_by_name(). + * + * \subsection client_subsec Clients + * + * The only operation supported on clients, is the possibility of kicking + * them off the server using pa_context_kill_client(). + */ + +/** \file + * + * Routines for daemon introspection. + */ + +PA_C_DECL_BEGIN + +/** Stores information about sinks */ +typedef struct pa_sink_info { + const char *name;

It is, however, very simple to use and + * quite sufficent for many programs. + * + * \section conn_sec Connecting + * + * The first step before using the sound system is to connect to the + * server.

The main difference is that they're call pa_simple_read() + * and pa_simple_write(). Note that these operations always block. + * + * \section ctrl_sec Buffer control + * + * If a playback stream is used then a few other operations are available: + * + * \li pa_simple_drain() - Will wait for all sent data to finish playing. + * \li pa_simple_flush() - Will throw away all data currently in buffers. + * \li pa_simple_get_playback_latency() - Will return the total latency of + * the playback pipeline. + * + * \section cleanup_sec Cleanup + * + * Once playback or capture is complete, the connection should be closed + * and resources freed.

Data is + * routed, converted and mixed from several sources before it is passed along + * to a final output. Currently, there are three forms of audio streams: + * + * \li Playback streams - Data flows from the client to the server. + * \li Record streams - Data flows from the server to the client. + * \li Upload streams - Similar to playback streams, but the data is stored in + * the sample cache. See \ref scache for more information + * about controlling the sample cache. + * + * \section create_sec Creating + * + * To access a stream, a pa_stream object must be created using + * pa_stream_new(). At this point the audio sample format and mapping of + * channels must be specified. See \ref sample and \ref channelmap for more + * information about those structures. + * + * This first step will only create a client-side object, representing the + * stream. To use the stream, a server-side object must be created and + * associated with the local object. Depending on which type of stream is + * desired, a different function is needed: + * + * \li Playback stream - pa_stream_connect_playback() + * \li Record stream - pa_stream_connect_record() + * \li Upload stream - pa_stream_connect_upload() (see \ref scache) + * + * Similar to how connections are done in contexts, connecting a stream will + * not generate a pa_operation object. Also like contexts, the application + * should register a state change callback, using + * pa_stream_set_state_callback(), and wait for the stream to enter an active + * state. + * + * \subsection bufattr_subsec Buffer Attributes + * + * Playback and record streams always have a server side buffer as + * part of the data flow. The size of this buffer strikes a + * compromise between low latency and sensitivity for buffer + * overflows/underruns. + * + * The buffer metrics may be controlled by the application. They are + * described with a pa_buffer_attr structure which contains a number + * of fields: + * + * \li maxlength - The absolute maximum number of bytes that can be stored in + * the buffer. If this value is exceeded then data will be + * lost. + * \li tlength - The target length of a playback buffer. The server will only + * send requests for more data as long as the buffer has less + * than this number of bytes of data. + * \li prebuf - Number of bytes that need to be in the buffer before + * playback will commence. Start of playback can be forced using + * pa_stream_trigger() even though the prebuffer size hasn't been + * reached. If a buffer underrun occurs, this prebuffering will be + * again enabled. If the playback shall never stop in case of a buffer + * underrun, this value should be set to 0. In that case the read + * index of the output buffer overtakes the write index, and hence the + * fill level of the buffer is negative. + * \li minreq - Minimum free number of the bytes in the playback buffer before + * the server will request more data. + * \li fragsize - Maximum number of bytes that the server will push in one + * chunk for record streams. + * + * The server side playback buffers are indexed by a write and a read + * index. The application writes to the write index and the sound + * device reads from the read index. The read index is increased + * monotonically, while the write index may be freely controlled by + * the application. Substracting the read index from the write index + * will give you the current fill level of the buffer. The read/write + * indexes are 64bit values and measured in bytes, they will never + * wrap. The current read/write index may be queried using + * pa_stream_get_timing_info() (see below for more information). In + * case of a buffer underrun the read index is equal or larger than + * the write index. Unless the prebuf value is 0, Polypaudio will + * temporarily pause playback in such a case, and wait until the + * buffer is filled up to prebuf bytes again. If prebuf is 0, the + * read index may be larger than the write index, in which case + * silence is played. If the application writes data to indexes lower + * than the read index, the data is immediately lost. + * + * \section transfer_sec Transferring Data + * + * Once the stream is up, data can start flowing between the client and the + * server. Two different access models can be used to transfer the data: + * + * \li Asynchronous - The application register a callback using + * pa_stream_set_write_callback() and + * pa_stream_set_read_callback() to receive notifications + * that data can either be written or read. + * \li Polled - Query the library for available data/space using + * pa_stream_writable_size() and pa_stream_readable_size() and + * transfer data as needed. The sizes are stored locally, in the + * client end, so there is no delay when reading them. + * + * It is also possible to mix the two models freely. + * + * Once there is data/space available, it can be transferred using either + * pa_stream_write() for playback, or pa_stream_peek() / pa_stream_drop() for + * record. Make sure you do not overflow the playback buffers as data will be + * dropped. + * + * \section bufctl_sec Buffer Control + * + * The transfer buffers can be controlled through a number of operations: + * + * \li pa_stream_cork() - Start or stop the playback or recording. + * \li pa_stream_trigger() - Start playback immediatly and do not wait for + * the buffer to fill up to the set trigger level. + * \li pa_stream_prebuf() - Reenable the playback trigger level. + * \li pa_stream_drain() - Wait for the playback buffer to go empty. Will + * return a pa_operation object that will indicate when + * the buffer is completely drained. + * \li pa_stream_flush() - Drop all data from the playback buffer and do not + * wait for it to finish playing. + * + * \section seek_modes Seeking in the Playback Buffer + * + * A client application may freely seek in the playback buffer. To + * accomplish that the pa_stream_write() function takes a seek mode + * and an offset argument. The seek mode is one of: + * + * \li PA_SEEK_RELATIVE - seek relative to the current write index + * \li PA_SEEK_ABSOLUTE - seek relative to the beginning of the playback buffer, (i.e. the first that was ever played in the stream) + * \li PA_SEEK_RELATIVE_ON_READ - seek relative to the current read index. Use this to write data to the output buffer that should be played as soon as possible + * \li PA_SEEK_RELATIVE_END - seek relative to the last byte ever written. + * + * If an application just wants to append some data to the output + * buffer, PA_SEEK_RELATIVE and an offset of 0 should be used. + * + * After a call to pa_stream_write() the write index will be left at + * the position right after the last byte of the written data. + * + * \section latency_sec Latency + * + * A major problem with networked audio is the increased latency caused by + * the network. To remedy this, Polypaudio supports an advanced system of + * monitoring the current latency. + * + * To get the raw data needed to calculate latencies, call + * pa_stream_get_timing_info(). This will give you a pa_timing_info + * structure that contains everything that is known about the server + * side buffer transport delays and the backend active in the + * server. (Besides other things it contains the write and read index + * values mentioned above.) + * + * This structure is updated every time a + * pa_stream_update_timing_info() operation is executed. (i.e. before + * the first call to this function the timing information structure is + * not available!) Since it is a lot of work to keep this structure + * up-to-date manually, Polypaudio can do that automatically for you: + * if PA_STREAM_AUTO_TIMING_UPDATE is passed when connecting the + * stream Polypaudio will automatically update the structure every + * 100ms and every time a function is called that might invalidate the + * previously known timing data (such as pa_stream_write() or + * pa_stream_flush()). Please note however, that there always is a + * short time window when the data in the timing information structure + * is out-of-date. Polypaudio tries to mark these situations by + * setting the write_index_corrupt and read_index_corrupt fields + * accordingly. + * + * The raw timing data in the pa_timing_info structure is usually hard + * to deal with. Therefore a more simplistic interface is available: + * you can call pa_stream_get_time() or pa_stream_get_latency(). The + * former will return the current playback time of the hardware since + * the stream has been started. The latter returns the time a sample + * that you write now takes to be played by the hardware. These two + * functions base their calculations on the same data that is returned + * by pa_stream_get_timing_info(). Hence the same rules for keeping + * the timing data up-to-date apply here. In case the write or read + * index is corrupted, these two functions will fail with + * PA_ERR_NODATA set. + * + * Since updating the timing info structure usually requires a full + * network round trip and some applications monitor the timing very + * often Polypaudio offers a timing interpolation system. If + * PA_STREAM_INTERPOLATE_TIMING is passed when connecting the stream, + * pa_stream_get_time() and pa_stream_get_latency() will try to + * interpolate the current playback time/latency by estimating the + * number of samples that have been played back by the hardware since + * the last regular timing update. It is espcially useful to combine + * this option with PA_STREAM_AUTO_TIMING_UPDATE, which will enable + * you to monitor the current playback time/latency very precisely and + * very frequently without requiring a network round trip every time. + * + * \section flow_sec Overflow and underflow + * + * Even with the best precautions, buffers will sometime over - or + * underflow. To handle this gracefully, the application can be + * notified when this happens. Callbacks are registered using + * pa_stream_set_overflow_callback() and + * pa_stream_set_underflow_callback(). + * + * \section sync_streams Sychronizing Multiple Playback Streams + * + * Polypaudio allows applications to fully synchronize multiple + * playback streams that are connected to the same output device. That + * means the streams will always be played back sample-by-sample + * synchronously.

For the basic design, see + * its documentation. + * + * The added feature in the threaded main loop is that it spawns a new thread + * that runs the real main loop. This allows a synchronous application to use + * the asynchronous API without risking to stall the Polypaudio library. + * + * \section creat_sec Creation + * + * A pa_threaded_mainloop object is created using pa_threaded_mainloop_new(). + * This will only allocate the required structures though, so to use it the + * thread must also be started. This is done through + * pa_threaded_mainloop_start(), after which you can start using the main loop. + * + * \section destr_sec Destruction + * + * When the Polypaudio connection has been terminated, the thread must be + * stopped and the resources freed. Stopping the thread is done using + * pa_threaded_mainloop_stop(), which must be called without the lock (see + * below) held. When that function returns, the thread is stopped and the + * pa_threaded_mainloop object can be freed using pa_threaded_mainloop_free(). + * + * \section lock_sec Locking + * + * Since the Polypaudio API doesn't allow concurrent accesses to objects, + * a locking scheme must be used to guarantee safe usage. The threaded main + * loop API provides such a scheme through the functions + * pa_threaded_mainloop_lock() and pa_threaded_mainloop_unlock(). + * + * The lock is recursive, so it's safe to use it multiple times from the same + * thread. Just make sure you call pa_threaded_mainloop_unlock() the same + * number of times you called pa_threaded_mainloop_lock(). + * + * The lock needs to be held whenever you call any Polypaudio function that + * uses an object associated with this main loop. Make sure you do not hold + * on to the lock more than necessary though, as the threaded main loop stops + * while the lock is held. + * + * Example: + * + * \code + * void my_check_stream_func(pa_threaded_mainloop *m, pa_stream *s) { + * pa_stream_state_t state; + * + * pa_threaded_mainloop_lock(m); + * + * state = pa_stream_get_state(s); + * + * pa_threaded_mainloop_unlock(m); + * + * if (state == PA_STREAM_READY) + * printf("Stream is ready!"); + * else + * printf("Stream is not ready!"); + * } + * \endcode + * + * \section cb_sec Callbacks + * + * Callbacks in Polypaudio are asynchronous, so they require extra care when + * using them together with a threaded main loop. + * + * The easiest way to turn the callback based operations into synchronous + * ones, is to simply wait for the callback to be called and continue from + * there. This is the approach chosen in Polypaudio's threaded API. + * + * \subsection basic_subsec Basic callbacks + * + * For the basic case, where all that is required is to wait for the callback + * to be invoked, the code should look something like this: + * + * Example: + * + * \code + * static void my_drain_callback(pa_stream*s, int success, void *userdata) { + * pa_threaded_mainloop *m; + * + * m = (pa_threaded_mainloop*)userdata; + * assert(m); + * + * pa_threaded_mainloop_signal(m, 0); + * } + * + * void my_drain_stream_func(pa_threaded_mainloop *m, pa_stream *s) { + * pa_operation *o; + * + * pa_threaded_mainloop_lock(m); + * + * o = pa_stream_drain(s, my_drain_callback, m); + * assert(o); + * + * while (pa_operation_get_state(o) != OPERATION_DONE) + * pa_threaded_mainloop_wait(m); + * + * pa_operation_unref(o); + * + * pa_threaded_mainloop_unlock(m); + * } + * \endcode + * + * The main function, my_drain_stream_func(), will wait for the callback to + * be called using pa_threaded_mainloop_wait(). + * + * If your application is multi-threaded, then this waiting must be done + * inside a while loop. The reason for this is that multiple threads might be + * using pa_threaded_mainloop_wait() at the same time. Each thread must + * therefore verify that it was its callback that was invoked. + * + * The callback, my_drain_callback(), indicates to the main function that it + * has been called using pa_threaded_mainloop_signal(). + * + * As you can see, both pa_threaded_mainloop_wait() may only be called with + * the lock held. The same thing is true for pa_threaded_mainloop_signal(), + * but as the lock is held before the callback is invoked, you do not have to + * deal with that. + * + * The functions will not dead lock because the wait function will release + * the lock before waiting and then regrab it once it has been signaled. + * For those of you familiar with threads, the behaviour is that of a + * condition variable. + * + * \subsection data_subsec Data callbacks + * + * For many callbacks, simply knowing that they have been called is + * insufficient. The callback also receives some data that is desired. To + * access this data safely, we must extend our example a bit: + * + * \code + * static int *drain_result; + * + * static void my_drain_callback(pa_stream*s, int success, void *userdata) { + * pa_threaded_mainloop *m; + * + * m = (pa_threaded_mainloop*)userdata; + * assert(m); + * + * drain_result = &success; + * + * pa_threaded_mainloop_signal(m, 1); + * } + * + * void my_drain_stream_func(pa_threaded_mainloop *m, pa_stream *s) { + * pa_operation *o; + * + * pa_threaded_mainloop_lock(m); + * + * o = pa_stream_drain(s, my_drain_callback, m); + * assert(o); + * + * while (pa_operation_get_state(o) != OPERATION_DONE) + * pa_threaded_mainloop_wait(m); + * + * pa_operation_unref(o); + * + * if (*drain_result) + * printf("Success!"); + * else + * printf("Bitter defeat..."); + * + * pa_threaded_mainloop_accept(m); + * + * pa_threaded_mainloop_unlock(m); + * } + * \endcode + * + * The example is a bit silly as it would probably have been easier to just + * copy the contents of success, but for larger data structures this can be + * wasteful. + * + * The difference here compared to the basic callback is the 1 sent to + * pa_threaded_mainloop_signal() and the call to + * pa_threaded_mainloop_accept(). What will happen is that + * pa_threaded_mainloop_signal() will signal the main function and then stop. + * The main function is then free to use the data in the callback until + * pa_threaded_mainloop_accept() is called, which will allow the callback + * to continue. + * + * Note that pa_threaded_mainloop_accept() must be called some time between + * exiting the while loop and unlocking the main loop! Failure to do so will + * result in a race condition. I.e. it is not ok to release the lock and + * regrab it before calling pa_threaded_mainloop_accept(). + * + * \subsection async_subsec Asynchronous callbacks + * + * Polypaudio also has callbacks that are completely asynchronous, meaning + * that they can be called at any time. The threading main loop API provides + * the locking mechanism to handle concurrent accesses, but nothing else. + * Applications will have to handle communication from the callback to the + * main program through some own system. + * + * The callbacks that are completely asynchronous are: + * + * \li State callbacks for contexts, streams, etc. + * \li Subscription notifications + */ + +/** \file + * + * A thread based event loop implementation based on pa_mainloop.
