delete a per-process timer (REALTIME)
POSIX Real-time Library (librt, -lrt)
timer_delete() system call deletes the specified
timer, timerid, previously created by the
timer_create(2) system call. If the timer is armed when
timer_delete() is called, the behavior is as if the
timer is automatically disarmed before removal. Pending signals for the
deleted timer are cleared.
Upon successful completion, the value 0 is returned; otherwise the
value -1 is returned and the global variable
errno is set to indicate the error.
timer_delete() system call will fail if:
- The timer ID specified by timerid is not a valid
timer_delete() system call conforms to
IEEE Std 1003.1-2004 (“POSIX.1”).
Support for POSIX per-process timer first appeared in FreeBSD
