* Name: timer_getoverrun
|
|
*
|
|
* Description:
|
|
* Only a single signal will be queued to the process for a given timer at
|
|
* any point in time. When a timer for which a signal is still pending
|
|
* expires, no signal will be queued, and a timer overrun will occur. When
|
|
* a timer expiration signal is delivered to or accepted by a process, if
|
|
* the implementation supports the Realtime Signals Extension, the
|
|
* timer_getoverrun() function will return the timer expiration overrun
|
|
* count for the specified timer. The overrun count returned contains the
|
|
* number of extra timer expirations that occurred between the time the
|
|
* signal was generated (queued) and when it was delivered or accepted, up
|
|
* to but not including an implementation-defined maximum of
|
|
* DELAYTIMER_MAX. If the number of such extra expirations is greater than
|
|
* or equal to DELAYTIMER_MAX, then the overrun count will be set to
|
|
* DELAYTIMER_MAX. The value returned by timer_getoverrun() will apply to
|
|
* the most recent expiration signal delivery or acceptance for the timer.
|
|
* If no expiration signal has been delivered for the timer, or if the
|
|
* Realtime Signals Extension is not supported, the return value of
|
|
* timer_getoverrun() is unspecified.
|
|
*
|
|
* Input Parameters:
|
|
* timerid - The pre-thread timer, previously created by the call to
|
|
* timer_create(), whose overrun count will be returned..
|
|
*
|
|
* Returned Value:
|
|
* If the timer_getoverrun() function succeeds, it will return the timer
|
|
* expiration overrun count as explained above. timer_getoverrun() will
|
|
* fail if:
|
|
*
|
|
* EINVAL - The timerid argument does not correspond to an ID returned by
|
|
* timer_create() but not yet deleted by timer_delete().
|
|
*
|
|
* Assumptions:
|
|
