traffic counter in linux or bsd

Hi.

What is the simple way to do a traffic counter in C ?
I'm searching but there aren't any records of total transffers in /proc
to get the value.

Thanks in advance.

What is the simple way to do a traffic counter in C ?

Does it have to be able to handle multiple lanes? Does it have
to be able to figure out how many axels the trucks have? Does it
have to be able to handle bicycles? Does it have to be able to handle
when vehicles encounter the counting device at an angle?

I'm searching but there aren't any records of total transffers in /proc
to get the value.

The C standards don't just not know anything about /proc :
the C standards don't have any concept of "transfers".

Possibly you should inquire in sci.engr.civil or
comp.programming.embedded -- or one of the human resources
newsgroups might be able to help with assessing total transfers.

Sorry. I didn't give the right question.
I was asking about network traffic in a network interface:

I have a firewall that when it reachs the 2GB limits it must close the
interface and activate again in day 1 of each month.

I have already done the daemon with forks and i was starting to code
the main() but I can't find the any numbers of traffic already done in
/proc or ifconfig.

Any help please ?

Well, like I said, the C standards don't know anything about /proc .
They don't know anything about ifconfig either. Or daemons, or forks,
or networks, or interfaces, or firewalls.

Have you tried the obvious: reading the netstat source code ?

Not here. Standard C, which is what we discuss here, has no way to do
what you're asking for. Try comp.unix.programmer.

And learn to post proper followups.

Whatever it is it is apparently off topic, but without proper
context it is hard to tell where to send you. You should have
monitored the newsgroup for a period to discover the subject of
discussion, which in this case is the _standard_ C language.

In this particular case it doesn't matter too much, but in general
on usenet you should realize that readers may very well not have
convenient access to previous articles in a thread. That means
that your reply articles should include adequate context, so that
they stand by themselves. Google is NOT usenet, it is only a very
poor interface to the real usenet system. To include proper
context when using google, see my sig. below. Please be sure to
read the referenced URLs.
