What is the correct format of getopt() and how does it work? I looked
at the man page; it doesn't really clarify things. What's a program
that uses it, maybe I could figure it out from that.
Note: This is on-topic. getopt is part of the standard library.

man 3 getopt

man getopt

Note: getopt is certainly *NOT* part of the standard library; I don't
know where you got that idea. Questions such as yours which are not
related to ISO standard C should be directed to a group where they'd be
on-topic, such as comp.programming, one of the gnu. hierarchy, or perhaps
a Linux programming group.

libc is not the standard C library (i.e., the library defined by the C
language standard).
C is a language; Unix is an operating system. C is not Unix; Unix is
not C.

That library doesn't exist! The only C is the one people actually use.

P.S. As far as getopt(), I wrote some test programs and I think I have
figured it out. It doesn't really work well with a ':' other than at
the end, though. I think anyone who's serious about processing command
lines would write his own modification. k_**********@yahoo.com writes: Keith Thompson wrote: > ??? It is in libc. Maybe it's Unix-specific, but C is Unix.

The topic of this newsgroup is the C language as defined by the
standard (which doesn't include getopt). If you want to discuss
something else, there are other newsgroups; in comp.unix.programmer,
for example, they're far more likely to be able to answer your
questions than we are.

So what do you call Windows3.1 then? Unix??? It certainly was written
in C as much as any variant of Unix were.
I've written on systems where their libc includes support for CANbus
and ARCnet but I recognise that they were vendor specific additions to
libc. Just because gcc has its own extended libc doesn't mean that ALL
C compilers need to emulate it to conform to C standards (ANSI, C99,
etc). k_**********@yahoo.com wrote: Note: This is on-topic. getopt is part of the standard library.

did you notice that you are the only person in this thread that thinks

It is not just bureaucratese.
If write a program in ANSI C, then you can guarantee that it will compile
and run on any system with a ANSI C compiler. If it doesn't you can complain
to the compiler vendor, and he will either have to post a fix or remove the
claim to ANSI compatibility.
On the other hand if you use a non-standard function like getopt(), you may
end up having to implement it youself. There is no getopt() on my Windows C
compiler, for instance. C is a language; Unix is an operating system. C is not Unix; Unix is not C.
I know that, obviously. But C is written for Unix and vice versa.
They grew up together. And C works more nicely on Unix than any other
system. However only a minority of my C programs have been for Unix - most
are either Windows or games console programs.

getopt is defined in the Standard Unix Specification, not ANSI C.
The online SUSv3 description has example usage: http://www.opengroup.org/onlinepubs/...ns/getopt.html
And of course, there are about a gazillion Free Software programs out there
that use getopt, all with viewable, usable and redistributable source code.
Direct any questions to comp.unix.programmer.

So are lots of things platform-specific.
Maybe it's Unix-specific,
It may be POSIX, but you'd have to ask in a unix group to find out.
but C is Unix.
Not since about 1970. Get with the right millenium

Maybe once upon a time, C was targettted at an early version of unix ,
but that was 30-odd years ago. Unix certainly was never written for
C.
The first proper rockets were targetted at london, does that make the
shuttle 'for' london, and vice-versa?

Well, there's no such thing as "the one people actually use", because
there is no "the" C compiler. There are many C compilers available, and
most (if not all) include extensions to the standard. Those extensions
(of which getopt is one) are off-topic here.
There is, however, something called "the" C language, and that is what
is discussed here. (Well, there have been several revisions to "the"
language.)
And, one of the C compilers that I actually use shows:
==========
C:\temp>cl foo.c
Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 12.00.8804 for 80x86
Copyright (C) Microsoft Corp 1984-1998. All rights reserved.
foo.c
Microsoft (R) Incremental Linker Version 6.00.8447
Copyright (C) Microsoft Corp 1992-1998. All rights reserved.
/out:foo.exe
foo.obj
foo.obj : error LNK2001: unresolved external symbol _getopt
foo.exe : fatal error LNK1120: 1 unresolved externals
==========
I don't care for bureaucratic s*** here more than anywhere else.
And off-topic posts aren't welcome here more than anywhere else.
I can hear a lot of plonking going on over that sentence. C is a language; Unix is an operating system. C is not Unix; Unix is not C.
I know that, obviously. But C is written for Unix and vice versa.
Since when? C, as defined in the standard and discussed in this group,
doesn't even require an O/S. (It doesn't even require a keyboard and
display.)
P.S. As far as getopt(), I wrote some test programs and I think I have figured it out. It doesn't really work well with a ':' other than at the end, though. I think anyone who's serious about processing command lines would write his own modification.
Or ask for help in a group where this discussion is not off-topic.
