help:Infrared Communication

I would like to write an infrared application using Visual C++ 6.0 and
Windows xp,

#include <winsock2.h>

#include <af_irda.h>

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

#define IR_SERVICE_NAME "MyServer"
#define MAX_BUFFER 4096

DWORD WINAPI ClientThread(LPVOID lpParam)
{
    SOCKET s = (SOCKET)lpParam;
    int ret;
    char szRecvBuff[MAX_BUFFER];

    while (1)
    {
        //
        // Read data from client
        //

        if ((ret = recv(s, szRecvBuff, MAX_BUFFER, 0)) == SOCKET_ERROR)
        {
            printf("recv failed with error %d\n", WSAGetLastError());
            break;
        }

        if (ret == 0)
            break;

        printf("Successfully received %d bytes\n", ret);

        //
        // Echo data back to client
        //

        if ((ret = send(s, szRecvBuff, ret, 0)) == SOCKET_ERROR)
        {
            printf("send failed with error %d\n", WSAGetLastError());
            break;
        }

        printf("Successfully sent %d bytes\n", ret);
    }

    printf("Closing connection\n");

    closesocket(s);
    return 0;
}

#ifdef _WIN32_WCE
int WINAPI WinMain(HANDLE hInstance, HANDLE hPrevIntance,
                   LPTSTR lpCmdLine, int nCmdShow)
#else
void main(int argc, char **argv)
#endif
{
    WSADATA wsd;
    SOCKET sock,
                  sockClient;
    SOCKADDR_IRDA irAddr = {AF_IRDA, 0, 0, 0, 0, "\0"},
                  remoteIrAddr;
    int iIrSize = sizeof(SOCKADDR_IRDA);
    DWORD dwId;
    BOOL bDone=FALSE;
    HANDLE hThread;
    WORD wVersion;

#ifdef _WIN32_WCE
    wVersion = MAKEWORD(1,1);
#else
    wVersion = MAKEWORD(2,2);
#endif

    if (WSAStartup(wVersion, &wsd) != 0)
    {
        printf("Unable to load Winsock library!\n");
        return;
    }

    if ((sock = socket(AF_IRDA, SOCK_STREAM, 0)) == INVALID_SOCKET)
    {
        printf("socket failed with error %d\n", WSAGetLastError());
        return;
    }

    strcpy(irAddr.irdaServiceName, IR_SERVICE_NAME);

    //
    // Bind our socket to the local service name
    //
    printf("Binding to service class name: %s\n",
irAddr.irdaServiceName);

    if (bind(sock, (struct sockaddr *)&irAddr, sizeof(SOCKADDR_IRDA))
== SOCKET_ERROR)
    {
        printf("bind failed with error %d\n", WSAGetLastError());
        return;
    }

    listen(sock, 10);

    printf("Bound and listening\n");

    while (1)
    {
        if ((sockClient = accept(sock, (struct sockaddr
*)&remoteIrAddr, &iIrSize)) == SOCKET_ERROR)
        {
            printf("accept failed with error %d\n", WSAGetLastError());
            return;
        }

        printf("Accepted a connection\n");

        // Process I/O in a seperate thread.

        hThread = CreateThread(NULL, 0, ClientThread,
(LPVOID)sockClient, 0, &dwId);

        CloseHandle(hThread);
    }

    // Close and cleanup
    //
    closesocket(sock);

    WSACleanup();
}

but when I compile a existing program,the error:f"atal error C1083:
Cannot open include file: 'af_irda.h': No such file or directory".I
have added ws2_32.lib but also cann't find the definition of af_irda.
thank you every much.
