I am trying to port a project (from linux) that uses Semaphores to Mac OS X however some of the posix semaphores are not implemented on Mac OS X

The one that I hit in this port is sem_timedwait()

I don't know much about semaphores but from the man pages sem_wait() seems to be close to sem_timedwait and it is implemented

From the man pages

sem_timedwait() function shall lock the semaphore referenced by
sem as in the sem_wait() function. However, if the semaphore cannot be
locked without waiting for another process or thread to unlock the
semaphore by performing a sem_post() function, this wait shall be ter-
minated when the specified timeout expires

From my limited understanding of how semphores work I can see that sem_timedwait() is safer, but I still should be able to use sem_wait()

Is this correct? If not what other alternatives do I have...

Thanks
