I think you shall see Libpcap:
http://www.tcpdump.org/

But thake care .. I think you shall write your code in C not C++ then

are you saying libpcap doesn't compile with g++?

if you use libpcap (written in C) in a c++ program i think you should use

extern "C"
{
#include <pcap.h>
}

i hope it works.
good luck

P.S. look at this link if you want to mix c and c++ progs:

you can use any c liblary or function under c++ also you can use old and new style include sytax together...
extern "C"
{
#include <pcap.h>
}
you should not need that
