[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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 CAutoLock class holds a critical section for the scope of a code block.
This class works in conjunction with the CCritSec class, which is a wrapper for critical section objects. The CAutoLock constructor locks the critical section, and the destructor unlocks it. By using a CAutoLock object as a local variable, you can lock a critical section with the guarantee that all code paths will unlock the critical section.
The following code example shows how to use this class:
CCritSec csMyLock; // Critical section is not locked yet.
{
CAutoLock cObjectLock(&csMyLock); // Lock the critical section.
// Protected section of code.
} // Lock goes out of scope here.
The methods in this class are not designed to be overridden.
