KSDDKAPI KSOBJECTTYPE KsGetObjectTypeFromIrp(

A pointer to the IRP structure for which to find the associated AVStream object type.
KsGetObjectTypeFromIrp returns the type of AVStream object associated with the given IRP as a KSOBJECTTYPE enumeration. This is one of the following: KsObjectTypeDevice, KsObjectTypeFilterFactory, KsObjectTypeFilter, KsObjectTypePin.
The KsGetObjectTypeFromIrp function does not check that the I/O request packet (IRP) is associated with a KS object. If it is not, this may result in a memory access error. Driver developers should consider using structured exception handling to catch a possible exception.
