gd_invalid_dirfile — obtain an pointer to an invalid DIRFILE object

       The  gd_invalid_dirfile() returns a pointer to a newly allocated, invalid DIRFILE object.  Like any other
       DIRFILE object, the invalid DIRFILE object should be de-allocated by calling gd_close(3) or gd_discard(3)
       when it is no longer needed.

       The DIRFILE object returned may be passed to any other GetData function which requires one, but doing  so
       will inevitably result in that function failing with the GD_BAD_DIRFILE error.

       A similar effect can be achieved by making an invalid gd_open(3) call, such as:

              gd_open("", 0);

       which  also  returns  a  pointer to an invalid DIRFILE object.  The difference is that an invalid DIRFILE
       created in this way has a non-zero error code (obtainable with gd_error(3)), while the dirfile  error  of
       the invalid DIRFILE returned by gd_invalid_dirfile(3) is zero (indicating success).

       The gd_invalid_dirfile() function appeared in GetData-0.7.0.

       gd_invalid_dirfile — obtain an pointer to an invalid DIRFILE object

       This  function  always  returns a pointer to a newly allocated, invalid DIRFILE object, except when it is
       unable to allocate memory for the DIRFILE, in which case it returns NULL.
