The FsRtlIsPagingFile routine determines whether a given file is a paging file.

Syntax

LOGICAL FsRtlIsPagingFile(
  [in] PFILE_OBJECT FileObject
);

Parameters

[in] FileObject

Pointer to a file object for the file.

Return value

FsRtlIsPagingFile returns TRUE if the file represented by FileObject is a paging file, otherwise FALSE.

Remarks

File system filter drivers call FsRtlIsPagingFile to determine whether a given file object represents a paging file.

Note If FsRtlIsPagingFile is called in the create completion ("post-create") path, it returns FALSE, even if the file is a paging file. However, it works properly on Windows Vista and later.
