pcap_fileno - get the file descriptor for a live capture
SYNOPSIS
#include <pcap/pcap.h>
int pcap_fileno(pcap_t *p);
DESCRIPTION
If p refers to a network device that was opened for a live capture using a combination of pcap_create() and pcap_activate(), or using
pcap_open_live(), pcap_fileno() returns the file descriptor from which captured packets are read.
If p refers to a ``savefile'' that was opened using functions such as pcap_open_offline() or pcap_fopen_offline(), a ``dead'' pcap_t opened
using pcap_open_dead(), or a pcap_t that was created with pcap_create() but that has not yet been activated with pcap_activate(), it
returns -1.

I want to write a small application using Libpcap in C on Linux.
Currently, it starts to sniff and waits for the packets. But that's not what I need actually. I want it to wait for N seconds and then stop listening. (I think there's something wrong with my usage of 'pcap_open_live'...)

Hi all
My application is a monitoring application that monitors the incoming udp packet when ever required. When ever a particular source ip and port and dest ip and port is provided the filter will be framed based them. For eg,
