[PATCH] posix: New function posix_spawn_file_actions_addchdir_np [BZ #17405]
- From: Florian Weimer <fweimer at redhat dot com>
- To: libc-alpha at sourceware dot org
- Date: Fri, 26 Oct 2018 16:07:20 +0200
- Subject: [PATCH] posix: New function posix_spawn_file_actions_addchdir_np [BZ #17405]
I'm not adding documentation in this patch because none exists for the
posix_spawn functionality.
I initially copied posix/spawn_faction_addchdir.c from
posix/spawn_faction_addopen.c, hence the backdated copyright notice.
If we agree that this is the way to go, I will add further such
functions (fchdir, chroot, perhaps more).
Thanks,
Florian
