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.
