Put the question in the body of your message, not just in the subject
line.  You've been told this before; why do you refuse to listen?

The comp.lang.c FAQ is at <http://www.c-faq.com/>.  You have just
asked question 19.16.  You should have checked the FAQ before posting.

There is no way in standard C to create or remove a directory.
C does not have the concept of directories in any of its operations.
Anything you want to do to manipulate directories will have to be
done through a system-specific call. Check in a newsgroup that
deals with whatever operating system you are using.

Not portable.

Umesh, read this carefully.  Pay attention this time.

Please do not top-post.  The concept of top-posting, and the reasons
for not doing it, are explained in the following links:

    http://www.caliburn.nl/topposting.html
    http://www.cpax.org.uk/prg/writings/topposting.php

You are being rude.  If you continue to top-post, I will never answer
another of your questions.

Brilliant - for the second time in the thread, he replies to someone
by simply restating his need for help.

Killfile him, fellas, you know it makes sense.

Use 'remove' or 'unlink'. The former is a libray function while latter
is system call under unix. Both does the same.

Not correct on all Unix like systems since I've seen remove described
for off-topic reasons as sometimes calling unlink and sometimes another
function. remove is part of the Standard C library, unlink may or may
not be a system call but certainly is not part of the standard library.

Not defined by Standard C.

And hence /not portable/. If you're going to tell people unportable
things, have the decency to tell them they're unportable.

I'm not convinced.
