Is there any possible way to use sockets in C, so i can finish a
instant messenger program?

Odd question, considering the basic API is in C. For details, ask on
comp.unix.progr ammer

First step: Search the C standard for the word 'socket'. If
found, read the associated text. If not found, abandon the idea or
develop (or steal) the needed protocols somewhere.

That's not a particularly useful answer. There are plenty of things
that can be done in perfectly portable standard C that aren't
mentioned in the standard.

A much more useful response would be to redirect the OP to
comp.unix.progr ammer (which, as it happens, Ian Collins already did).

Yes, of course. Just
#include <sys/types.h>
#include <sys/socket.h>
then use socket(), connect(), listen(), send(), etc. as required.

Post again if you have any specific queries about any of the socket
functions, or how they're used.

Does that mean it's not possible to implement linked lists in C, since
linked lists are not mentioned in the standard?
Steal is a heavy word. It's certainly not stealing to use a free POSIX
implementation of BSD sockets (which most unix systems have)

Under windows you can use the sockets interface provided by
Microsoft with the windows SDK. It is very similar to the
Unix interface anyway.

By similar, don't you actually mean identical? I thought Microsoft had
just used the BSD code directly?

No, my answer was not very helpful. The point is that there is
nothing in the C standard or library to implement sockets. You
have to first define what you want, and then implement it in
standard C code, to be on-topic in this newsgroup. Linked lists
are simpler, and more easily defined, but the same process
applies. Code to implement it will be sufficienly short for
publication in c.l.c.

Other groups, such as comp.software-eng, might be more helpful,
especially for sockets..

Then why bother posting it?

More to the point, why bother posting it five hours after the OP had
been redirected to an appropriate group?

Pay no attention of Antoninus Twink. He has long established himself as
an antisocial troll with the goal of destroying this newsgroup. He
knows that _every one_ of his suggested headers and functions is
off-topic, and he knows that there are newsgroups devoted to sockets
programming and bsd where your questions have better chances of getting
useful answers. His invitation to you to continue posting about these
questions here is, in fact, an invitation to join him in this crusade to
destroy comp.lang.c and to join him in countless killfiles.

Yes, the question was off-topic. Presumably the original poster
didn't know that. An appropriate response would have simply to
redirect the OP to a group where it *is* on-topic, not to send him on
a while goose chase to try (and fail) to find a standard C way of
implementing sockets.

If I accidentally wander into a butcher shop and ask for spark plugs,
just tell me where the auto parts store is. You *know* I'm not really
looking for spark plugs made out of meat; don't waste my time
suggesting that I'd be in the right place if I were.

And, again, I think comp.unix.progr ammer, not comp.software-eng, is
more likely to be the right place. Next most likely is one of the
Windows groups, but the user name "4.4.bsd" suggests Unix.

The absolute, gob-smacking irony of Marty Ambuhl calling anybody
"anti-social" is completely beyond the pale.

Apparently, you seem to think there is some chance of his succeeding.

Not to mention the irony of your commenting on someone you claim to have
killfiled. Seems your boat has sprung a leak.

The language itself has no support for sockets. However, there are
many packages which implement support for sockets by providing
specialized headers and run time libraries. These are of necessity
system specific. Ask in a newsgroup where your system is topical
(e.g., comp.unix.progr ammer).
