timer_delete — delete a per-process timer (REALTIME)
POSIX Real-time Library (librt, -lrt)
#include <time.h> int timer_delete(timer_t timerid);
The 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.
The timer_delete() system call will fail if: [EINVAL] The timer ID specified by timerid is not a valid timer ID.
The timer_delete() system call conforms to IEEE Std 1003.1-2004 (“POSIX.1”).
Support for POSIX per-process timer first appeared in FreeBSD 7.0.
