[Ramiro Rodriguez]

In C there is a function to easily parse command line arguments called
getopt. Is there such a function in c++

No there is not. Your implementation might
provide one as an extension, but it's not
part of standard C.
Is there such a function in c++

No. If you decide to try to write one, we
can help.

IINM, C++ can call any C function.

But I'm not sure that getopt is part of standard C or C++.

But quite recently I wrote a command line reader class that might be to
your needs (depending on what your needs are). I'll try and get it put
up somewhere soon.

1) getopt is part of the POSIX standard, not the ANSI C OR C++ standards.

2) You should be able to call it from a C++ program with no problems.

It's now up, complete with a bit of documentation (just under 8K in total):

I don't think so.

I used Google

http://www.google.com/

to search for

+"C++" +"class GetOpt"

and found lots of stuff including
C++ version of the GNU getopt function
http://cclib.nsu.ru/projects/gnudocs...libg++_39.html

Hope this helps.

you may want to try GNU Gengetopt that I personally maintain:

http://www.gnu.org/software/gengetopt/

This program generates a C function that uses getopt_long function to
parse the command line options, to validate them and fills a struct

I use it also inside C++ programs :-)

hope this helps
