CCritSec.Lock 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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.]
The Lock method locks the critical section object.
Syntax
void Lock();
Parameters
This method has no parameters.
Return value
This method does not return a value.
Remarks
This method calls the EnterCriticalSection function.
Call the CCritSec::Unlock member function to unlock the critical section. You can make multiple calls to the Lock method on the same thread; be sure to call Unlock a corresponding number of times.
If the object is already locked by another thread, the CCritSec::Lock method blocks until the object is released, or until a possible-deadlock exception occurs.
