It doesn't matter if the function fails (I'm not sure if it's even possible), because the read data isn't used for anything and the daemon will terminate in any case. The void cast should get rid of a Coverity warning. Removing the whole pa_read() call should be ok too, but I guess it's nice to clean up the pipe before terminating... --- src/daemon/cpulimit.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) diff --git a/src/daemon/cpulimit.c b/src/daemon/cpulimit.c index 3a97297..0abbac0 100644 --- a/src/daemon/cpulimit.c +++ b/src/daemon/cpulimit.c @@ -167,7 +167,7 @@ static void callback(pa_mainloop_api*m, pa_io_event*e, int fd, pa_io_event_flags pa_log("Received request to terminate due to CPU overload."); - pa_read(the_pipe[0], &c, sizeof(c), NULL); + (void) pa_read(the_pipe[0], &c, sizeof(c), NULL); m->quit(m, 1); /* Quit the main loop */ } -- 1.7.8
