Update.
1998-09-17 19:34 Ulrich Drepper <drepper@cygnus.com> * sysdeps/unix/sysv/sysv4/bits/utsname.h: Fix typo. Patch by John Tobey <jtobey@banta-im.com>. 1998-09-17 Mark Kettenis <kettenis@phys.uva.nl> * login/pty-internal.h: Removed. Moved constants related to the `grantpt' helper program protocol to ... * login/pty-private.h: ... here. New file. * sysdeps/unix/sysv/linux/ptsname.c (ptsname): Reimplementation to make the function work with kernels >= 2.1.115. * sysdeps/unix/sysv/linux/getpt.c (getpt): Reimplement to call BSD version if using the cloning device fails. * sysdeps/unix/sysv/linux/grantpt.c: New file. * sysdeps/unix/sysv/linux/unlockpt.c: General cleanup. * sysdeps/unix/bsd/getpt.c (__getpt): Largely rewritten to allow use by Linux specific code. * sysdeps/unix/bsd/unlockpt.c: General cleanup. * sysdeps/unix/grantpt.c: Largely rewritten. (pts_name): New function. (grantpt): Use pts_name, check group and permission mode in addition to owner. Try to set the owner, group and permission mode first without invoking the helper program. * login/programs/pt_chown.c: Largely rewritten. Add argp and internationalization support. Use symbolic constants instead of hardwired numbers for permission mode. * sysdeps/unix/bsd/ptsname.c: New file. 1998-09-17 22:04 Tim Waugh <tim@cyberelk.demon.co.uk> * posix/wordexp-test.c: Undo last change. * posix/wordexp.c: Undo last change.
