CMsgThread.SuspendThread method
[The feature associated with this page, DirectShow, is a legacy feature. It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer, IMFMediaEngine and Audio/Video Capture in Media Foundation instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
Uses the Microsoft Win32 SuspendThread function to suspend the operation of a running thread.
Syntax
DWORD SuspendThread();
Parameters
This method has no parameters.
Return value
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.
Remarks
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.
