ClfsTerminateReadLog function (wdm.h)
The ClfsTerminateReadLog routine invalidates a specified read context after freeing resources associated with the context.
CLFSUSER_API NTSTATUS ClfsTerminateReadLog(
[in] PVOID pvCursorContext
);
[in] pvCursorContext
A pointer to the read context to be invalidated. The caller previously obtained this pointer by calling ClfsReadLogRecord or ClfsReadRestartArea.
ClfsTerminateReadLog returns STATUS_SUCCESS if it succeeds; otherwise, it returns one of the error codes defined in Ntstatus.h.
Advarsel!
Failure to call this routine can lead to memory leaks, premature exhaustion of log I/O blocks, and increased frequency of log flushes. Attempting to use pvCursorContext after it is freed is equivalent to accessing freed memory and can lead to unexpected behavior.
