KsFilterAcquireProcessingMutex function (ks.h)
The KsFilterAcquireProcessingMutex function acquires the processing mutex for a specified AVStream filter.
Syntax
void KsFilterAcquireProcessingMutex(
[in] PKSFILTER Filter
);
Parameters
[in] Filter
A pointer to the KSFILTER structure representing the AVStream filter for which to acquire the processing mutex.
Return value
None
Remarks
AVStream holds the processing control mutex upon return from this routine. For more information, see Mutexes in AVStream.
A minidriver that must suspend processing for a long period of time should not use this mechanism. Instead, it should manipulate the processing control gate directly by using the KSGATEXxx functions.
