% man mutex
No manual entry for mutex


if you want the man page for pthread_mutexes, try
pthread_mutex_init. but that won't help since some implementations of
pthreads don't support cross-process mutexes.

if you want something "better" than a lock file, use a semaphore,
which is a standardized (though very cryptically documented) IPC
system for unix-like OS's. see man semop.
