Help- basic WinSock application

[tom_bali]

Hi
I want to write a basic server in C.

I compiled this code-
http://msdn.microsoft.com/en-us/libr...93(VS.85).aspx
and i got these problems:

d:\program files\microsoft visual studio\myprojects\server\server.c(18) : error C2079: 'hints' uses undefined struct 'addrinfo'
d:\program files\microsoft visual studio\myprojects\server\server.c(33) : error C2224: left of '.ai_family' must have struct/union type

d:\program files\microsoft visual studio\myprojects\server\server.c(56) : error C2198: 'bind' : too few actual parameters
Error executing cl.exe.

in summary, the struct "addrinfo" is undefined.

I included :

#include <stdio.h>
#include <winsock2.h>
#include <ws2tcpip.h>
#include <stdlib.h

I'm doing link to Ws2_32.lib(by writing it in project-settings-libar)

I'm working in Visual Studio 6.

Please help me

Thanks and sorry about my english
Tom.

Moved to Networking/Device Communication.

try including ws2_32.lib

[lolguy]

#pragma comment(lib,"ws2_32.lib") i think should work then

[vart]

try including ws2_32.lib

this is not a linker problem - it is compiler problem

I would try to move winsock2 include to be the first one in the list

i tried your 2 solutions, but it doesnt work ..

Have you at all modified the code, compared to the web-site?

What version of Visual Studio are you using?

I just copied and pasted it into a new, empty projects in VS C++ 2008 Express Ed., and it compiled, linked and ran without problems. I don't have any client to talk to it, so I don't know what it actually does.

msv6 got problems with it i tried it didnt compile with msv6 but it did with msv8

[abachler]

#include <winsock.h>

not winsock2.h

I noticed the program has

int __cdecl main(void)

Never seen anything like that before.

I thought the syntax was

int main(void)
