1. DO these work?
2. Do i need to loop RECV or will it keep recv till it recvs a buffer?
#include <winsock.h>
#include <stdio.h>
#include <iostream>
int main(int argc, char** argv) {
WORD version = MAKEWORD(1,1);
WSADATA wsaData;
int nRet;
char* IP=new char[32];
std::cin>>IP;
//
// Start up Winsock as before
//
WSAStartup(version, &wsaData);
//
// Store information about the server
//
LPHOSTENT lpHostEntry;
lpHostEntry = gethostbyname(IP); // Specifying server by its name
if (lpHostEntry == NULL) {
printf("Error at gethostbyaddr()\n");
WSACleanup();
system("pause");
return 0;
}
//

//

theSocket = socket(AF_INET, // Go over TCP/IP

if (theSocket == INVALID_SOCKET) {
printf("Error at socket()\n");
WSACleanup();

return 0;

//
// Use SOCKADDR_IN to fill in address information

if (nRet == SOCKET_ERROR) {

WSACleanup();

return 0;
}else{

}
// Successfully connected!
