Date: Thu, 5 Apr 2012 15:55:08 -0700 From: Isaac Dunham <idunham@...abit.com> To: musl@...ts.openwall.com Subject: Namespace issues, missing functions, _BSD_SOURCE for unistd.h Attached is a patch that should add proper BSD_SOURCE support for <unistd.h>. I'm not sure that the formatting/style is proper, and the exact arrangement is rather arbitrary. But I've moved a lot of things that were wrongly grouped in either ANSI namespace or GNU-only namespace. BSD || XOPEN means the macro test should be #if defined(_BSD_SOURCE) || defined(_XOPEN_SOURCE) I see glibc turns on both of these with _GNU_SOURCE. Misplaced (should be BSD || XOPEN): (Properly, these require XOPEN >= 500) usleep, ualarm, fchown, fchdir, lchown,vhangup, apparently fsync? Missing (BSD || XOPEN): getwd,ttyslot,sethostid,get/setdomainname,revoke,profil,acct,get/end/setusershell BSD||GNU: setlogin, getpass These and chroot also should be available with lower values of _XOPEN_SOURCE Incompatible: BSD uses setpgrp the same way everyone else uses setpgid--a substitution macro will do the job. That's what glibc does and what I did. And there may be one or two more that I didn't mention in here because I lost track.
