2006-10-03getopt_ulflags -> getopt32.Denis Vlasenko
It is impossible to formulate sane ABI based on size of ulong because it can be 32-bit or 64-bit. Basically it means that you cannot portably use more that 32 option chars in one call anyway... Make it explicit.

2006-09-23passwd: getopt_ulflags'isationDenis Vlasenko
2006-09-06removed a lot of trailing \n in bb_msg() calls. It is addedDenis Vlasenko
automatically by function itself.
2006-08-03Remove bb_ prefixes from xfuncs.c (and a few other places), consolidateRob Landley
things like xasprintf() into xfuncs.c, remove xprint_file_by_name() (it only had one user), clean up lots of #includes... General cleanup pass. What I've been doing for the last couple days. And it conflicts! I've removed httpd.c from this checkin due to somebody else touching that file. It builds for me. I have to catch a bus. (Now you know why I'm looking forward to Mercurial.)

2004-09-02Tito writes:Eric Andersen
Hi Erik, Hi to all, This is part five of the my_get*id story. I've tweaked a bit this two functions to make them more flexible, but this changes will not affect existing code. Now they work so: 1) my_getpwuid( char *user, uid_t uid, int bufsize) if bufsize is > 0 char *user cannot be set to NULL on success username is written on static allocated buffer on failure uid as string is written to buffer and NULL is returned if bufsize is = 0 char *user can be set to NULL on success username is returned on failure NULL is returned if bufsize is < 0 char *user can be set to NULL on success username is returned on failure an error message is printed and the program exits 2) 1) my_getgrgid( char *group, uid_t uid, int bufsize) if bufsize is > 0 char *group cannot be set to NULL on success groupname is written on static allocated buffer on failure gid as string is written to buffer and NULL is returned if bufsize is = 0 char *group can be set to NULL on success groupname is returned on failure NULL is returned if bufsize is < 0 char *group can be set to nULL on success groupname is returned on failure an error message is printed and the program exits This changes were needed mainly for my new id applet. It is somewhat bigger then the previous but matches the behaviour of GNU id and is capable to handle usernames of whatever length. BTW: at a first look it seems to me that it will integrate well (with just a few changes) with the pending patch in patches/id_groups_alias.patch. The increase in size is balanced by the removal of my_getpwnamegid.c from libbb as this was used only in previous id applet and by size optimizations made possible in whoami.c and in passwd.c. I know that we are in feature freeze but I think that i've tested it enough (at least I hope so.......).
