The name of a dirfile is the path- name passed to gd_cbopen() or gd_open() when the dirfile was opened. The dirfile argument must point to a valid DIRFILE object previously created by a call to gd_open(3). RETURN VALUE
Upon successful completion, gd_dirfilename() returns a pointer to a constant string containing the pathname of the dirfile. On error, gd_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 gd_error(3). A descriptive error string for the last error encountered can be obtained from a call to gd_error_string(3). SEE ALSO
