On Win32 how do you move a thread to another CPU core?

Question

I'd like to make sure that a thread is moved to a specific CPU core and can never be moved from it by the scheduler.

There's a SetThreadAffinityMask() call but there's no GetThreadAffinityMask().

The reason I need this is because high resolution timers will get messed up if the scheduler moves that thread to another CPU.

Answer 1

You should probably just use SetThreadAffinityMask and trust that it is working.
