+ * 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.
+ *
+ * Parameters:
+ *   timerid - The per-thread timer, previously created by the call to
+ *   timer_create(), to be deleted.
+ *
+ * Return 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:
+ *
