|Microsoft DirectX 9.0|
Uses the Microsoft Win32 SuspendThread function to suspend the operation of a running thread.
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.
The client thread calls this member function to suspend the operation of the worker thread. The worker thread remains suspended and will not execute until an additional call to the CMsgThread::ResumeThread member function is made.
