Cross-platform way of yielding a thread in C/C++?

Question

In C and C++ is there a cross-platform way of yielding a thread? Something like sched_yield() or Sleep(0)? Does SDL_Delay(0) always yield or will it return immediately in so

Answer 1

in the c++ case, boost::thread::yield() does what you ask. On platforms with posix threads, pthread_yield() performs the same function for C and anything that links with it. On platforms where this doesn't immediately stop the thread and start another, it's because the scheduler doesn't support that functionality. I don't think that many such platforms actually exist in the wild.
