The FsRtlSupportsPerStreamContexts macro determines whether a file system supports per-stream contexts for a given file stream.

Syntax

BOOLEAN FsRtlSupportsPerStreamContexts(
  [in] PFILE_OBJECT FileObject
);

Parameters

FileObject [in]
A pointer to a file object for the file stream.

Return value

The FsRtlSupportsPerStreamContexts macro returns TRUE if the file system supports per-stream contexts for the file stream, FALSE otherwise.

Remarks

File system filter drivers call FsRtlSupportsPerStreamContexts to determine whether the underlying file system supports per-stream contexts for the file stream represented by a given file object. Note that a file system might support per-stream contexts for some types of files but not for others. For example, NTFS and FAT do not currently support per-stream contexts for paging files.

For more information, see Tracking Per-Stream Context in a Legacy File System Filter Driver.
