void main()
{
int nByte;
char buf[35565];
struct sockaddr from;
int fromlen
//start winsock;I omit them
SOCKET sk=socket(AF_INET,SOCK_RAW,IPPROTO_TCP);
while(1)
{
nByte=recvfrom(sk,buf,sizeof(buf),0,&from,&fromlen);

Just take from www.codeguru.com/network/ipmon.html to compare.
The better place to ask such questions -
microsoft.public.win32.programmer.networks
