timer_delete - delete a per-process timer (REALTIME)
The timer_delete() function deletes the specified timer, timerid, previously created by the timer_create() function. If the timer is armed when timer_delete() is called, the behavior shall be as if the timer is automatically disarmed before removal. The disposition of pending signals for the deleted timer is unspecified.
If successful, the timer_delete() function shall return a value of zero. Otherwise, the function shall return a value of -1 and set errno to indicate the error.
The timer_delete() function may fail if:
- The timer ID specified by timerid is not a valid timer ID.

First released in Issue 5. Included for alignment with the POSIX Realtime Extension.
The timer_delete() function is marked as part of the Timers option.
The [ENOSYS] error condition has been removed as stubs need not be provided if an implementation does not support the Timers option.
IEEE Std 1003.1-2001/Cor 2-2004, item XSH/TC2/D6/139 is applied, updating the ERRORS section so that the [EINVAL] error becomes optional.
