* 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:
|
|
*
