Wed Jun 19 10:21:24 1996 Miles Bader <miles@gnu.ai.mit.edu> * hurd/hurdlookup.c (__hurd_file_name_lookup_retry, __hurd_file_name_lookup, __hurd_file_name_split): Add & use LOOKUP argument. Rename nested function lookup to lookup_op. (__file_name_lookup, __file_name_lookup_under): Pass 0 for lookup arg to __hurd_file_name_lookup. (__file_name_split): Likewise for __hurd_file_name_split. * hurd/path-lookup.c (hurd_file_name_path_lookup): Add LOOKUP argument. Rename nested function lookup to scan_lookup. (file_name_path_lookup): Pass 0 for lookup arg to hurd_file_name_path_lookup. * hurd/hurd/lookup.h (__hurd_file_name_lookup, hurd_file_name_lookup, __hurd_file_name_lookup_retry, hurd_file_name_lookup_retry: __hurd_file_name_split, hurd_file_name_split, hurd_file_name_lookup): Add LOOKUP argument. * sysdeps/mach/hurd/access.c (__access): Pass 0 lookup arg to __hurd_file_name_lookup.

The second callback function GET_DTABLE_PORT should behave like `getdport'.
