WebThis provides similar functionality to the POSIX pthread_join() function. See also sleep() and terminate(). bool QThread:: wait (unsigned long time) This is an overloaded function. time is the time to wait in milliseconds. If time is ULONG_MAX, then the wait will never timeout.

You can wake a pause () d thread with pthread_kill () to send some signal that won't kill it ( SIGCONT seems appropriate). Though if you're expecting threads to cooperate, you should look into conditions and mutexes. # 3 harvard divinity school field education
