visual studio 2005 c++ and TCHAR/unicode

Martyr

i can't get this code to compile for 64-bit, that isn't really the problem for the first error though.

#define WIN32_LEAN_AND_MEAN

#define _WIN32_WINNT 0x0502

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

#pragma comment (lib, "ws2_32.lib")

int _tmain(int argc, _TCHAR* argv[])
{
	WSADATA wsa;
	ADDRINFO aiHints,*aiEntry,*aiList=NULL;
	SOCKET s;

	if(--argc == 2) {
		if((WSAStartup(MAKEWORD(2,0),&wsa))==ERROR_SUCCESS) {
			ZeroMemory(&aiHints,sizeof(aiHints));

			aiHints.ai_family   = AF_INET;
			aiHints.ai_socktype = SOCK_STREAM;
			aiHints.ai_protocol = IPPROTO_TCP;

			if((getaddrinfo(argv[1],argv[2],&aiHints,&aiList)) == 0) {
				for(aiEntry=aiList;aiEntry != NULL;aiEntry=aiEntry->ai_next) {
					if((s=socket(aiEntry->ai_family,aiEntry->ai_socktype,aiEntry->ai_protocol)) != SOCKET_ERROR) {
						if((connect(s,aiEntry->ai_addr,aiEntry->ai_addrlen)) != SOCKET_ERROR) {
							wprintf(L"\nconnected...");
						} else wprintf(L"\nconnect() failed");
						closesocket(s);
					}
				} freeaddrinfo(aiList);
			} else wprintf(L"\ngetaddrinfo(%s) failed",argv[1]);
		}
	} else wprintf(L"\n\tUsage:%s <ip/host> <port>\n",argv[0]);
	return 0;
}

Error	1	error C2664: 'WspiapiGetAddrInfo' : cannot convert parameter 1 from '_TCHAR *' to 'const char *'	d:\Documents and Settings\Administrator\My Documents\Visual Studio 2005\Projects\tcp\tcp\tcp.cpp	28	
Warning	2	warning C4267: 'argument' : conversion from 'size_t' to 'int', possible loss of data	d:\Documents and Settings\Administrator\My Documents\Visual Studio 2005\Projects\tcp\tcp\tcp.cpp	31

i don't want to cast argv[1] and argv[2] with (const char*) as these are unicode arguements.UNICODE and _UNICODE are defined in the command line.

i checked the api WspiapiGetAddrInfo

#define getaddrinfo             WspiapiGetAddrInfo

...

int
WINAPI
WspiapiGetAddrInfo(
    IN const char                       *nodename,
    IN const char                       *servname,
    IN const struct addrinfo            *hints,
    OUT struct addrinfo                 **res)
{

but in the platform SDK documentation its defined like

int getaddrinfo(
  const TCHAR* nodename,
  const TCHAR* servname,
  const struct addrinfo* hints,
  struct addrinfo** res
);

by the way, i'm using Windows 2003 R2 SDK, anyone know what i'm doing wrong?

Can i hell figure it out. But then again the only 64bit pc i have access to is in work

Here may help

i was using the MSDN 2005 with version of visual studio 2005 pro edition.
there must be error in docs i have, because on msdn site,the api is defined as:

int WSAAPI getaddrinfo(
  const char* nodename,
  const char* servname,
  const struct addrinfo* hints,
  struct addrinfo** res
);

and it goes onto to say anyone programming unicode should use GetAddrInfoW or GetAddrInfo with UNICODE or _UNICODE defined.

i just downloaded the sp1 sdk,will try it later and see if that works.
thanks nutjob.
