WinSock -- Next Hurdle =oD
Alright, so here I am reading all I can on winsock and when I finally try out some examples I get undefined errors from the linkers output (i'm using Dev C++ 4 by Bloodshed). I run WinXP pro and I think that could be the problem or maybe it's something else? Thought maybe you fine people could help.
Here's the example I was trying out from "Johnnies Winsock Tutorial"
PHP Code:
#include <winsock.h> // winsock.h always needs to be included
#include <stdio.h>
int main(int argc, char** argv) {
WORD version = MAKEWORD(1,1);
WSADATA wsaData;
int nRet;
//
// First, we start up Winsock
//
WSAStartup(version, &wsaData);
//
// Next, create the socket itself
//
SOCKET listeningSocket;
listeningSocket = socket(AF_INET, // Go over TCP/IP
SOCK_STREAM, // Socket type
IPPROTO_TCP); // Protocol
if (listeningSocket == INVALID_SOCKET) {
printf("Error at socket()");
return 0;
}
//
// Use SOCKADDR_IN to fill in address information
//
SOCKADDR_IN saServer;
saServer.sin_family = AF_INET;
saServer.sin_addr.s_addr = INADDR_ANY; // Since this is a server, any address will do
saServer.sin_port = htons(8888); // Convert int 8888 to a value for the port field
//
// Bind the socket to our local server address
//
nRet = bind(listeningSocket, (LPSOCKADDR)&saServer, sizeof(struct sockaddr));
if (nRet == SOCKET_ERROR) {
printf("Error at bind()");
return 0;
}
//
// Make the socket listen
//
nRet = listen(listeningSocket, 10); // 10 is the number of clients that can be queued
if (nRet == SOCKET_ERROR) {
printf("Error at listen()");
return 0;
}
//
// Wait for a client
//
SOCKET theClient;
theClient = accept(listeningSocket,
NULL, // Wait for a specific address to connect; here there is none
NULL);
if (theClient == INVALID_SOCKET) {
printf("Error at accept()");
return 0;
}
// Send/receive from the client, and finally:
closesocket(theClient);
closesocket(listeningSocket);
//
// Shutdown Winsock
//
WSACleanup();
}
The Errors..

Bleh.. Any ideas anyone?
