<p>We have multiple MFC apps, which use CMutex( false, "blah" ), where "blah" allows the mutex to work across process boundaries.</p>

<p>One of these apps was re-written without MFC (using Qt instead).  How can I simulate the CMutex using Win32 calls? (Qt's QMutex is not inter-process.)  I prefer not to modify the MFC apps.</p>

The following funcs will probably be what you want, they are all documented on MSDN.
```
```
CreateMutex(...)
WaitForSingleObject(...)
ReleaseMutex(...)
```
```
