* \section intro_sec Introduction
* This document describes the client API for the PulseAudio sound
* server. The API comes in two flavours to accommodate different styles
* of applications and different needs in complexity:
* \li The complete but somewhat complicated to use asynchronous API
* \li The simplified, easy to use, but limited synchronous API
* All strings in PulseAudio are in the UTF-8 encoding, regardless of current
* locale. Some functions will filter invalid sequences from the string, some
* will simply fail. To ensure reliable behaviour, make sure everything you
* pass to the API is already in UTF-8.
* \section simple_sec Simple API
* Use this if you develop your program in synchronous style and just
* need a way to play or record data on the sound server. See
* \subpage simple for more details.
* \section async_sec Asynchronous API
* Use this if you develop your programs in asynchronous, event loop
* based style or if you want to use the advanced features of the
* PulseAudio API. A guide can be found in \subpage async.
* By using the built-in threaded main loop, it is possible to acheive a
* pseudo-synchronous API, which can be useful in synchronous applications
* where the simple API is insufficient. See the \ref async page for
* \section thread_sec Threads
* The PulseAudio client libraries are not designed to be directly
* thread-safe. They are however designed to be reentrant and
* To use the libraries in a threaded environment, you must assure that
* all objects are only used in one thread at a time. Normally, this means
* that all objects belonging to a single context must be accessed from the
* same thread.
* The included main loop implementation is also not thread safe. Take care
* to make sure event objects are not manipulated when any other code is
* using the main loop.
* \section pkgconfig pkg-config
* The PulseAudio libraries provide pkg-config snippets for the different
* \li libpulse - The asynchronous API and the internal main loop implementation.
* \li libpulse-mainloop-glib - GLIB 2.x main loop bindings.
* \li libpulse-simple - The simple PulseAudio API.
