There are rather basic (producer/consume queues) and as some have pointed out, are buggy. I'd highly suggest looking at Boost's threading library (for an example of an object oriented approach to threading, taking advantage of RAII -- much of it is now standard in C++11), Intel's Thread Building Blocks, Java's built in Concurrency Utilities (java.util.concurrent package), Doug Lea's Fork Join Framework. The a great book on the subject is Maurice Herlihy's The Art of Multiprocessor Programming:
The book is in Java, but C++11 has the required primitives (cross platform compare and set for integral types, a defined memory model) so you could follow allong in C++11.
