/* c file called test.c*/

#include <linux/netfilter.h>
#include <libipq.h>
#include <stdio.h>

int main()
{
  int retVal = 0;
  char buf[1000];
  struct ipq_handle* userHandle;

  userHandle = ipq_create_handle(0, PF_INET);
  if(userHandle == NULL)
  {
    printf("ipq_create_handle returned error\n");
    return -1;
  }

  retVal = ipq_read(userHandle, buf, 1000, 0);

  return 0;
}

my problem is how shall I include all these header files , so that my program works

any hints and suggestions
prethanks to helper

Does the file exist on you harddrive? If not:
Do you have the iptables-devel & libnet packages installed?

sounds like you dont have the libraries installed. probably want to use your package manager (yum, pup, whatever) to get it.. you can get it straight from Subversion, if you dont mind trusting their malformed ssl certificate
https://svn.netfilter.org/netfilter/trunk/iptables/libipq/

you probably also need the <socket.h> header. this should be standard with gcc.
