Well here ya go, I finally picked it up again, I was doing other stuff before. Include ws2_32.lib and it should compile fine under almost any C++ compiler.
If it compiles fine, but if you get 15 "unresolved external symbols" - Include ws2_32.lib!
Code:
#include <iostream.h>
#include <winsock2.h>
#include <windows.h>
#include <ws2tcpip.h>
#define SIO_RCVALL _WSAIOW(IOC_VENDOR,1)

void displayudp(char *packet, char *logfile, int *option);
void displayicmp(char *packet, char *logfile, int *option);
