  • directory:

    The search path directory. For a list of possible values, see Searchpathdirectory.

  • domainMask:

    The file system domain to search. Specify 0 for this parameter if you want the file manager to choose the domain that is most appropriate for the specified url.

Discussion

Use this method to determine the relationship between an item and one of the system-specific directories. For example, you might use this method to determine if the specified item is in the user’s Documents directory or is in the trash. If the relationship between the items is determined successfully, this method sets the value of the outRelationship parameter to an appropriate value. The directory may contain the item, it may be the same as the item, or it may not have a direct relationship to the item.
