CSource::pStateLock (Compact 2013)

3/26/2014

Retrieves a pointer to the filter-critical section.

Syntax

CCritSec* pStateLock(void);

Parameters

None.

Return Value

Returns the critical section.

Remarks

Locking consists of holding the filter-critical section by calling the pStateLock member function and using the returned object to serialize access to functions.

Typically, this lock can be held by a function when the worker thread might want to hold it. Therefore, to access a shared state from the worker thread, add another critical-section object.

The exception occurs during the processing loop of the thread when it is safe to retrieve the filter-critical section from within CSourceStream::FillBuffer.
