# 217704 21-Jan-2011 jilles

getgroups(2): Remove mention of <sys/param.h> and refer to sysconf(3).

Because {NGROUPS_MAX} may become variable, its value should be obtained
using sysconf(3). If a #define is used anyway, it should be obtained by
including <limits.h> as that is in POSIX like getgroups(2) itself is.
<sys/param.h> is not in POSIX.

Just like in case of setgroups(2), for getgroups(2) also advice including
sys/param.h instead of sys/types.h so we get NGROUPS_MAX and NGROUPS
definitions.


# 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.

Per Regents of the University of Calfornia letter, remove advertising
clause.

# If I've done so improperly on a file, please let me know.

mdoc(7) police: "The .Fa argument.".


# 108028 18-Dec-2002 ru

mdoc(7) police: Tidy up the syscall language.

Stop calling system calls "function calls".

Use "The .Fn system call" a-la "The .Nm utility".

When referring to a non-BSD implementation in
the HISTORY section, call syscall a function,
to be safe.


# 84306 01-Oct-2001 ru

mdoc(7) police: Use the new .In macro for #include statements.


# 79754 15-Jul-2001 dd

Remove whitespace at EOL.

mdoc(7) police: removed HISTORY info from the .Os call.

# 44478 05-Mar-1999 bde

Backed out most of rev.1.4. I didn't submit it; I only submitted a
request for it something like it. It was poorly worded and too
far from both POSIX wording and normal (mal)practice by referring to
sysconf(_SC_NGROUPS_MAX) instead of {NGROUPS_MAX} or NGROUPS. POSIX.1
uses curly braces to mark up "symbolic constants or limits [that may
be] defined in certain headers". Since we don't document this markup,
don't use it. Just use NGROUPS_MAX.


# 32489 13-Jan-1998 alex

Dump the constant NGROUPS in favor of the POSIX way:
sysconf(_SC_NGROUPS_MAX).

Submitted by: bde


# 32448 11-Jan-1998 alex

Replace sys/param.h with sys/types.h as per POSIX.
Document the special case of gidsetlen == 0.

Partially obtained from: OpenBSD


# 17782 22-Aug-1996 mpp

Correctly use .Fn instead of .Nm to reference function names
in a bunch of man pages.

Use the correct .Bx (BSD UNIX) or .At (AT&T UNIX) macros
instead of explicitly specifying the version in the text
in a bunch of man pages.
