WinSock -- Next Hurdle =oD

[Trippin_On_X]

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"

#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?

u have to link to ws2_32.lib i think it is. i dont know how u do that in ur compiler though.

[Trippin_On_X]

That was pretty dull of me, heh it said I needed to link it right up top. Thanks

[nabeels786]

its wsock32.lib

[PsyVision]

It depends, wsock32.lib is for winsock 1.1/2 i think and and ws2_32.lib u have to use if u are using winsock version 2 or higher
