Or do we need to have any specific library ?

I am more interested in knowing if we can do string pattern matching
regular expression processing with C.

Not in standard C, there are plenty of extensions (POSIX regex for
example).

I disagree, one most certainly can.

There are no functions for doing this in the standard library, so one
would have to either write them, or find a library that already
contained them. But such a library could be written in strictly
conforming C, at least for the ASCII character set.

Didn't you see the clarification I posted an hour earlier?

Quite possibly not, since Usenet is a best-effort, asynchronous
distribution system that makes absolutely no promises whatsoever that
any specific message will reach any given server in any particular
amount of time. Depending on the route it has to take, the newsgroup(s)
it's posted to, the time of day it was posted, and many other variables
including how the destination server (and any servers between the one
you posted on and the destination) is configured, a message you post to
your news server might be seen on a different server within seconds. Or
it could take anywhere from minutes to weeks to get there. Assuming it
ever makes the trip at all...
