This is standard C library stuff really, but since I hate when people give that answer... You don't need to create a thread for this, just use alarm() and you'll get a SIGALRM. >From there, you can post to a semaphore or whatever. See: http://docs.linux.cz/programming/c/unix_examples/alarm.html But, since you asked, if you don't want to use alarm(), like you have some other work that could be done in the thread, you could do this: --- SNIP --- volatile int global_TerminateAlarmThread = 0; sem_t global_AlarmEvent; /* Initialized in main() */ void * alarm_thread_main(void *arg) { int *pSeconds = (int *) arg; while(!global_TerminateAlarmThread) { /* Uses CLOCK_REALTIME here - watch out for time/date changes */ sleep(*pSeconds); sem_post(&global_AlarmEvent); } pthread_exit(0); return 0; } --- END --- It's sort of what the kernel does anyhow for you though, except using signals...
