Mutual Exclusion - quick question

[Jen53403]

Sorry if this is a bad question, but I'm trying to implement some mutual exclusion between processes in C++. I'm aware of the acquire() and enterCriticalSection() functions which are supposed to accomplish this, but I get an error saying these functions are undefined when I try either of them. I assume I'm missing a .h file or something. Do I have to create an instance of a class, or can I just include whatever .h file I need, and what .h file is that? Thanks so much.

Those are windows routines. I don't know of any critical sections in Unix. At most, it is shared memory with a semaphore lock on it. Have a look at

for the Unix IPC mechanisms.
