Semaphores in c++

[josephellengar]

Hello, I am currently working on a programming assignment using multiple threads. I completely understand what I'm doing and how to do it, with one exception. It has to use semaphores, and I can't for the life of me figure out what #include statements I have to use to get semaphores to work. All of the sample code that I find online is for c, rather than c++. So far, I am only using #include<pthread> for the multithreading part. Anyway, do you have any suggestions?

Thanks!

Hiya.
You could have a look at the boost library:

It's an assignment. I'm required to use POSIX.

Can you use librt and Posix semaphore.h?

Sorry, thought this was a different thread. Yeah, I had already figured this out. I'm using semaphore.h and I found a site that gave the syntax I need. http://www.csc.villanova.edu/~mdamian/threads/posixsem.html
