You're trying to use Winsock version 1 and 2 at the same time.

To fix it, remove these lines:
1
2
 
#include<WinSock.h>
#pragma comment (lib, "Mswsock.lib")

Move Windows.h after winsock2.h

You need to initialise the sockets library before you use it with:
1
2
 
WSADATA wsadata;
WSAStartup(MAKEWORD(2, 2), &wsadata);

This has no meaning on Windows:
 
 
"/proc/%d/net/tcp"

I haven't confirmed it, but that should do it.

EDIT: This is really bad as fp is uninitialised.

    FILE *fp;

    if (fp != 0)
