Locks the critical section object.
void Lock( );
Parameters
None.
Return Values
None.
Remarks
This member function locks the critical section object.
You can make multiple lock calls on the same thread, but the CCritSec::Unlock member function must be called a corresponding number of times before the object is unlocked.
If the object is locked by another thread, the CCritSec::Lock member function blocks until either the object is released or a "possible deadlock" exception occurs.
Requirements
DirectShow applications and DirectShow filters have different include file and link library requirements.
For more information, see Setting Up the Build Environment.
OS Versions: Windows CE 2.12 and later. Version 2.12 requires DXPAK 1.0 or later.
