GioFiledup

Duplicates a GFile handle. This operation does not duplicate the actual file or directory represented by the GFile; see g_file_copy() if attempting to copy a file.

g_file_dup() is useful when a second handle is needed to the same underlying file, for use in a separate thread (GFile is not thread-safe). For use within the same thread, use g_object_ref() to increment the existing object’s reference count.

This call does no blocking I/O.
