| H A D | timers.h | diff 151869 Sun Oct 30 01:56:08 MDT 2005 davidxu Let itimer store itimerspec instead of itimerval, so I don't have to convert to or from timeval frequently. Introduce function itimer_accept() to ack a timer signal in signal acceptance code, this allows us to return more fresh overrun counter than at signal generating time. while POSIX says: "the value returned by timer_getoverrun() shall apply to the most recent expiration signal delivery or acceptance for the timer,.." I prefer returning it at acceptance time. Introduce SIGEV_THREAD_ID notification mode, it is used by thread libary to request kernel to deliver signal to a specified thread, and in turn, the thread library may use the mechanism to implement SIGEV_THREAD which is required by POSIX. Timer signal is managed by timer code, so it can not fail even if signal queue is full filled by sigqueue syscall. |
