It depends on what you actually want walk_dir() to do.

a) According to the current documentation, the first parameter should be
   a path name. At least on DOS and Windows, something that contains a
   wildcard is not a valid path name.
   Yes, if the first parameter actually is supposed to be a path name,
   then I would expect that the user-defined routine would not be called
   at all because no such directory as "C:\\*.txt" exists, and that
   walk_dir() spits out an error message.

b) On the other hand, if it is intended that the first parameter of
   walk_dir() may contain wildcards, then the documentation should be
   changed accordingly. And the walk_dir() function must be changed, so
   that -- regarding my previous example -- onyly "C:" is given to the
   user-defined function as the path name, rather than "C:\\*.txt",
   because "C:\\*.txt" is not a path name.
