Determines whether a tag's associated reparse point is a surrogate for another named entity (for example, a mounted folder).
The reparse point tag to be tested for surrogacy.
A nonzero return value means that the tag indicates a surrogate reparse point. A zero return value means that the tag does not indicate a surrogate reparse point.
If the surrogacy bit is set, the file or directory represents another named entity in the system, such as a mounted folder that associates this directory with another volume. For more information on volume mounting, see Mounted Folders.
