Mutual Exclusion - quick question

Mutual Exclusion - quick question

Mutual Exclusion - quick question

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.

RE: Mutual Exclusion - quick question

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 http://www.ecst.csuchico.edu/~beej/guide/ipc/ for the Unix IPC mechanisms.
