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. - * - * Parameters: - * timerid - The pre-thread timer, previously created by the call to - * timer_create(), whose overrun count will be returned.. - * - * Return 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: - * - ********************************************************************************/ - -int timer_getoverrun(timer_t timerid) -{ - errno = ENOSYS; - return ERROR; -} - -#endif /* CONFIG_DISABLE_POSIX_TIMERS */ |
