 * Function:  timer_gettime
 *
 * Description:
 *  The timer_gettime() function will store the amount of time until the
 *  specified timer, timerid, expires and the reload value of the timer into the
 *  space pointed to by the value argument. The it_value member of this structure
 *  will contain the amount of time before the timer expires, or zero if the timer
 *  is disarmed. This value is returned as the interval until timer expiration,
 *  even if the timer was armed with absolute time. The it_interval member of
 *  value will contain the reload value last set by timer_settime().
 *
 * Parameters:
 *   timerid - The pre-thread timer, previously created by the call to
 *   timer_create(), whose remaining time count will be returned..
 *
 * Return Value:
 *   If the timer_gettime() succeeds, a value of 0 (OK) will be returned.
 *   If an error occurs, the value -1 (ERROR) will be returned, and errno set to
 *   indicate the error.
 *
 *   EINVAL - The timerid argument does not correspond to an ID returned by
 *     timer_create() but not yet deleted by timer_delete().
 *
 * Assumptions:
 *
