hi

i have msdn tcp/ip sample :

#include "stdafx.h"
//int _tmain(int argc, _TCHAR* argv[])
//{
// return 0;
//}

#include "winsock2.h"

void main() {

// Initialize Winsock.
WSADATA wsaData;
int iResult = WSAStartup( MAKEWORD(2,2), &wsaData );
if ( iResult != NO_ERROR )
printf("Error at WSAStartup()\n");

// Create a socket.
SOCKET m_socket;
m_socket = socket( AF_INET, SOCK_STREAM, IPPROTO_TCP );

if ( m_socket == INVALID_SOCKET ) {
printf( "Error at socket(): %ld\n", WSAGetLastError() );
WSACleanup();
return;
}

// Connect to a server.
sockaddr_in clientService;

clientService.sin_family = AF_INET;
clientService.sin_addr.s_addr = inet_addr( "127.0.0.1" );
clientService.sin_port = htons( 27015 );

if ( connect( m_socket, (SOCKADDR*) &clientService,
sizeof(clientService) ) == SOCKET_ERROR) {
printf( "Failed to connect.\n" );
WSACleanup();
return;
}

// Send and receive data.
int bytesSent;
int bytesRecv = SOCKET_ERROR;
char sendbuf[32] = "Client: Sending data.";
char recvbuf[32] = "";

bytesSent = send( m_socket, sendbuf, strlen(sendbuf), 0 );

Whats wrong ?

This likely is not a standard C++ issue (as hinted at by the double
underscores in the conflicting identifiers), so you'll want to take it
to a Microsoft group. See this FAQ for some possibilities:

void main() is illegal. The program is ill formed, and therefore any
other problems are irrelevant.
