 a posix compliant function to read group database?
Hello to all,

Is it there a posix compliant function to read the group database?
I'm not sure if getgrent() is POSIX compliant...

Thank a lot to all of you in advance?

Depends what you mean by "POSIX." It's an X/Open function that's now in the
Single UNIX Specification (SUS), but I don't think it was in any POSIX
standard until 2001.

For systems that conform to UNIX98 or whatever SUS v3 will be called, it's
a required function, so using it is portable.

Its part of the XSI option within IEEE Std 1003.1-2001 and later
(the latest edition is 2003 which incorporates 2001 + technical
corrections).  A good description of the options and modularity of
POSIX.1-2001 is at
http://people.redhat.com/~drepper/posix-option-groups.html

Its been in the Single UNIX Specification since Version 1 (UNIX 95) -first
appearing in XSH  (System Interfaces and Headers) Issue 4 Version
2, which is the update that added the UX extension markings
when the UNIX trademark was transferred from Novell to X/Open (now
The Open Group) in 1994.
