A pointer to the KSFILTERFACTORY structure for which to find the first instantiated child filter.
KsFilterFactoryGetFirstChildFilter returns a pointer to the first instantiated KSFILTER structure created by FilterFactory. If there are no instantiated filters created by FilterFactory, NULL is returned.
This call is an inline function call to KsGetFirstChild. Note that the object hierarchy is guaranteed to be stable only while the appropriate mutex is held, in this case the device mutex. For more information, see Mutexes in AVStream.
