const char *dirfilename(const DIRFILE *dirfile);
DESCRIPTION

The dirfile argument must point to a valid DIRFILE object previously created by a call to dirfile_open(3).
RETURN VALUE
Upon successful completion, dirfilename() returns a pointer to a constant string containing the pathname of the dirfile. On error, dirfilename() returns NULL and sets the dirfile error to a non-zero value. Possible error values are:
GD_E_BAD_DIRFILE- The supplied dirfile was invalid. The dirfile error may be retrieved by calling
get_error(3). A descriptive error string for the last error encountered can be obtained from a call toget_error_string(3).
