Subject: [PATCH] alsactl: fix error handling for sched_setscheduler() call

As man page says: "If successful, the sched_setparam() function shall return zero."
|
||
|
|
||
|
Without update I got this output in the syslog (journalctl):
|
||
|
abr 16 09:25:30 mypc alsactl[1652]: alsactl 1.2.2 daemon started
|
||
|
abr 16 09:25:30 mypc alsactl[1652]: /usr/bin/alsactl: do_nice:165sched_setparam failed: No such file or directory
|
||
|
|
||
|
If sched_setscheduler() returns 0, so it means that the call was successful.
