Cross platform multithreading in C++?

Question

Basically, the title explains it all; I'm looking to make a game in C++ and I want to use multithreading for stuff like the physics engine and keeping the animation smooth on the loading screen. I've seen a few multithreading libraries, but I'm wondering which is best for my application, which will work well on Windows Mac and Linux. Does such a library exist?

Answer 1

You probably want boost::thread or Intels' Thread Building Blocks. I'd recommend TBB but it's not free, I think, so boost::thread for the free option.

Answer 2

If you can use c++0x threads, then use that.

If not, boost::thread is the best free multi-platform library.
