One way is to call pthread_mutex_init and check for an EBUSY error return. See the pthread_mutex_init man page for details. One could also keep track of initialization status (and which process initialized) in a variable in shared memory. Either ignore locking for setting that variable or try to deal with the chicken-or-egg issue. I still advise using a semaphore in preference to a mutex, or better still, avoid shared access entirely. _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
