and since (IIRC) linux/pthreads don't do this, you basically should never use a lock in this fashion at all! pthread_mutex_trylock() is fine. just avoid pthread_mutex_lock(). this does require that you have some fallback strategy: what to do if you can't take the lock. _______________________________________________ Linux-audio-dev mailing list [email protected] http://lists.linuxaudio.org/mailman/listinfo/linux-audio-dev
