Re: wsaData : undeclared identifier

Hard to say exactly, as you don't appear to have posted the complete compileable code that exhibits your problem.

> void main()

You use wsaData in the line above. Where is it declared? Is it somewhere before main() is called, or does it exist in a header file somewhere that is (or is supposed to be) included by your program?

Re: wsaData : undeclared identifier

I came across the following code that you posted in a different thread. Here wsaData is declared in the line I've highlighted:

(Toggle Plain Text)

#include <winsock.h>
#include <wsipx.h>
#include <wsnwlink.h>
#include <stdio.h>

int main()
{
////////////////
// Initialize windows sockets API.
//
WORD wVersionRequested = MAKEWORD(1, 1);
WSADATA wsaData;
if (WSAStartup(wVersionRequested, &wsaData)) {

Compare that with your post in this thread.
