From 860be2e70b33ff5eeb9130f80c4b1c096a2a8f27 Mon Sep 17 00:00:00 2001 From: Lennart Poettering Date: Fri, 14 Jul 2006 22:42:01 +0000 Subject: try to use send(,,MSG_NOSIGNAL) instead of write() wherever possible (which will allow us to drop the SIGPIPE check). Cache the results of the last write()/send() to make sure that we do not issue more than necessary system calls. git-svn-id: file:///home/lennart/svn/public/pulseaudio/trunk@1083 fefdeb5f-60dc-0310-8127-8f9354f1896f --- src/modules/module-jack-sink.c | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) (limited to 'src/modules/module-jack-sink.c') diff --git a/src/modules/module-jack-sink.c b/src/modules/module-jack-sink.c index 74f25d53..d761c1f7 100644 --- a/src/modules/module-jack-sink.c +++ b/src/modules/module-jack-sink.c @@ -80,6 +80,7 @@ struct userdata { jack_nframes_t frames_requested; int quit_requested; + int pipe_fd_type; int pipe_fds[2]; pa_io_event *io_event; @@ -120,7 +121,7 @@ static void io_event_cb(pa_mainloop_api *m, pa_io_event *e, int fd, pa_io_event_ assert(u); assert(u->pipe_fds[0] == fd); - read(fd, &x, 1); + pa_read(fd, &x, 1, &u->pipe_fd_type); if (u->quit_requested) { stop_sink(u); @@ -165,7 +166,7 @@ static void request_render(struct userdata *u) { assert(u); assert(u->pipe_fds[1] >= 0); - write(u->pipe_fds[1], &c, 1); + pa_write(u->pipe_fds[1], &c, 1, &u->pipe_fd_type); } static void jack_shutdown(void *arg) { @@ -268,6 +269,7 @@ int pa__init(pa_core *c, pa_module*m) { u->core = c; u->module = m; u->pipe_fds[0] = u->pipe_fds[1] = -1; + u->pipe_fd_type = 0; pthread_mutex_init(&u->mutex, NULL); pthread_cond_init(&u->cond, NULL); -- cgit
