delete a per-process timer (REALTIME)
POSIX Real-time Library (librt, -lrt)
() system call deletes the
specified timer, timerid
, previously created
by the timer_create(2)
system call. If the timer
is armed when
() 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
is set to indicate the error.
() system call will fail if:
- The timer ID specified by timerid is not
a valid timer ID.
() system call conforms to
IEEE Std 1003.1-2004
Support for POSIX per-process timer first appeared in FreeBSD
