Hi Hans,

If you don't care about portability, you can use a CriticalSection in win32.
But as Phil said, using an atomic FIFO is the preferred method.

Phil,

We should probably document that the callback will not be called
reentrantly(!) and make it an explicit requirement of all implementations.

Best wishes,

Ross.
