The KsGetObjectFromFileObject function returns the AVStream object cast to PVOID from FileObject.
Syntax
KSDDKAPI PVOID KsGetObjectFromFileObject(
[in] PFILE_OBJECT FileObject
);
Parameters
[in] FileObject
A pointer to the FILE_OBJECT structure for which to determine the associated AVStream object.
Return value
KsGetObjectFromFileObject returns a pointer to the AVStream object associated with FileObject (cast to PVOID). For example, this pointer may point to a KSFILTER or a KSPIN.
Remarks
The KsGetObjectFromFileObject function does not check that the file object 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.
