Re: 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.
