* Name: timer_delete
*
* Description:
* 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 timer will be automatically
* disarmed before removal. The disposition of pending signals for the
* deleted timer is unspecified.
*
* Input Parameters:
* timerid - The per-thread timer, previously created by the call to
* timer_create(), to be deleted.
*
* Returned Value:
* If the call succeeds, timer_create() will return 0 (OK). Otherwise,
* the function will return a value of -1 (ERROR) and set errno to
* indicate the error.
*
* EINVAL - The timer specified timerid is not valid.
*
* Assumptions:
