[Alsa-devel] exit() -> _exit() in pcm_direct.c

[Konstantin Stepaniuk]

Hello.

My program call snd_pcm_open() with "plug:dmix" in thread.
Function snd_pcm_direct_server_create() hangs on waitpid() if exit() is used, 
and server_job process keeps alive after program exit.
This trivial patch chages exit() to _exit() in file pcm_direct.c. In this case 
all works ok for me.

Best regards, Konstantin Stepaniuk.
