Hi,

Miguel,

For some time OSX has had Posix thread support including semaphores.


In that case, my app has a very strange behaviour on OSX, I make use of sem_init(), sem_wait() & sem_post(), and in OSX my threads never wait on sem_wait().

I googled after that problem and saw a lot of "OSX doesn't support POSIX Semaphores", after which I irresponsibly stopped looking for the cause of the problem. Apparently that could be the case in OSX 10.3, but I'm using 10.4.

Is there any kind of peculiarity in how I should use posix semaphores? (header files, semaphore inicialization or linker flags...)

In linux/ppc, I do not have this isssue..

ps.: if I'm in the wrong list (probably I am, where should I look for information/help?)
