The KsGetObjectTypeFromFileObject function returns the AVStream object type that is associated with a given file object.
Syntax
KSDDKAPI KSOBJECTTYPE KsGetObjectTypeFromFileObject(
[in] PFILE_OBJECT FileObject
);
Parameters
[in] FileObject
A pointer to the FILE_OBJECT structure for which to determine the associated AVStream object type.
Return value
KsGetObjectTypeFromFileObject returns the object type of the AVStream object associated with FileObject as a KSOBJECTTYPE enumeration. This can be one of the following: KsObjectTypeDevice, KsObjectTypeFilterFactory, KsObjectTypeFilter, or KsObjectTypePin.
