Critical Section Debugging Functions
[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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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.]
These functions help to debug critical sections in your code, which can make it easier to find the cause of a deadlock. These functions use the CCritSec helper class.
| Function | Description |
|---|---|
| CritCheckIn | Returns TRUE if the current thread owns the specified critical section. |
| CritCheckOut | Returns FALSE if the current thread owns the specified critical section. |
| DbgLockTrace | Enables or disables debug logging for a given critical section. |
