This API call allows the retrieval of the persistent object handle for any file object with the fully qualified file name. Also, any object's handle can be retrieved by its object ID string. Using the object's handle, its state can be manipulated with [[WinSetObjectData]], or delete the object with [[WinDestroyObject]].

Notes
This API call allows the retrieval of the persistent object handle for any file object with the fully qualified file name. Also, any object's handle can be retrieved by its object ID string. Using the object's handle, its state can be manipulated with WinSetObjectData, or delete the object with WinDestroyObject. Valid object ID strings start with the "<" character and end with the ">" character.
