|Microsoft DirectX 9.0|
Uses the Microsoft Win32 ResumeThread function to continue the operation of the worker thread after a previous call to the CMsgThread::SuspendThread member function.
If the member function succeeds, the return value is the previous suspend count of the thread. If the member function fails, the return value is 0xFFFFFFFF. To obtain extended error information, call the Microsoft Win32 GetLastError function.
