# 273717 27-Oct-2014 markj

getgrouplist(3) was reimplemented in terms of getgrent_r(3) in r174547, so
this bug is no longer valid.

# 194494 19-Jun-2009 brooks

In preparation for raising NGROUPS and NGROUPS_MAX, change base
system callers of getgroups(), getgrouplist(), and setgroups() to
allocate buffers dynamically. Specifically, allocate a buffer of size
sysconf(_SC_NGROUPS_MAX)+1 (+2 in a few cases to allow for overflow).

This (or similar gymnastics) is required for the code to actually follow
the POSIX.1-2008 specification where {NGROUPS_MAX} may differ at runtime
and where getgroups may return {NGROUPS_MAX}+1 results on systems like
FreeBSD which include the primary group.

In id(1), don't pointlessly add the primary group to the list of all
groups, it is always the first result from getgroups(). In principle
the old code was more portable, but this was only done in one of the two
places where getgroups() was called to the overall effect was pointless.

Document the actual POSIX requirements in the getgroups(2) and
setgroups(2) manpages. We do not yet support a dynamic NGROUPS, but we
may in the future.

Use the proper type (gid_t) for (group)->gr_gid to be orthogonal
with uid_t usage and (user)->pw_uid.

# 87054 28-Nov-2001 tobez

Do not write warning messages on stderr - a caller is expected to check
the return code and errno instead. Those warnings did not do any good
for daemonized users of initgroups(3), and confused cvs clients that
communicated with non-root cvs pserver.

The committed fix differs from the one suggested in the PR, and was
submitted by ru.

$Id$ -> $FreeBSD$


# 48794 12-Jul-1999 nik

Add $Id$, to make it simpler for members of the translation teams to
track.

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

.\" $Id$
.\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.
