KsGetObjectFromFileObject function (ks.h)

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.
