Interlocked and Memory Barriers

Question

I have a question about the following code sample (m_value isn\'t volatile, and every thread runs on a separate processor)

void Foo() // executed by thr         


        

Answer 1

I'm not completely sure but I think the Interlocked.Exchange will use the InterlockedExchange function of the windows API that provides a full memory barrier anyway.

This function generates a full memory barrier (or fence) to ensure that memory operations are completed in order.
