As you can see, there's some StaticMutex class also. I'm looking at the source right now, but I have still no idea why ordinary Mutex would be not good enough even for static variable of class.

Sorry.

The idea begind StaticMutex is this: Normal Mutex has intialization code in constructor. That might cause problems if you are using it as global variable - some global initialization (e.g. INITBLOCK) might try to lock uninitialized mutex.

StaticMutex is a simple wrapper that has no constructor and constructs itself at first call to Enter (in fact, it constructs a regular Mutex inside Smile

. However, it can only be used as static or global variable (because it employs initial zero initialization).
