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
(is not the same as)
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.programmin g, one of the gnu. hierarchy, or perhaps
a Linux programming group.

No it isn't.
??? It is in libc. Maybe it's Unix-specific, but C is Unix.

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.

We must do something. This is something. Therefore, we must do this.

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

I know that, obviously. But C is written for Unix and vice versa.

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_**********@ya hoo.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.progr ammer,
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_**********@ya hoo.com wrote: Note: This is on-topic. getopt is part of the standard library.

Is there any way to force getopt to process one option first?? I'd like to be able to pass in the name of a
configuration file for my application, then have the remaining command-line parameters over-ride the configuration file
if they are present.
For the moment, I'm restricted to 2.2 versions.
TIA . . . .

I tried to use getopt and copied the example from:
http://www.python.org/doc/current/lib/module-getopt.html
but nothing is working... getopt.GetoptError doesn't seem to exist and
when i run the program commenting this out, none of "-v", "-h" and
"-o" wants to be recognized... what's the matter?!

Hello,
In my use of getopt.getopt, I would like to make a certain parameter
mandatory. I know how to specify such that a parameter must have a value if
it's specified, but I also want to make the parameter itself
mandatory(combined with a mandatory value, the result is that the user must
specify a value).
Here's code illustrating my point(see the TODO):

Any hints?

I want to be able to do something like:
myscript.py * -o outputfile
and then have the shell expand the * as usual, perhaps to hundreds of
filenames. But as far as I can see, getopt can only get one argument
with each option. In the above case, there isn't even an option string
before the *, but even if there was, I don't know how to get getopt to
give me all the expanded filenames in an option.

They are compiled good on current linux machine.

The cause of problem is #include<getopt.h>.
