Thread: Opening a file and echoing the contents from it to the file descriptor

//and then what I think should be...
echoFile(connection_sckt, filename)
//which would cop the contents of filename to the connection_sckt(if this is in fact the correct fd)

You should post your whole code and let us look at it.

Trust me... simply calling accept does not open a socket.
And using fput() to echo characters to the socket handle does not send data.

Here's an example of what it takes to open a listening socket in Winsock...

Code:

// initialize Client port/return port number
WORD InitNetwork(WORD Port)
  { WSADATA     wsadata;              // winsock startup
    TCHAR       hn[MAX_HOSTNAME];     // host name
    DWORD       hs = MAX_HOSTNAME;    // host name size
    SOCKADDR    la;                   // local address
    WORD        lp = Port;            // local port
    // Load the Winsock DLL
    if (WSAStartup(MAKEWORD(2,0),&wsadata))
      return 0;
    // initialize local socket
    hSocket = socket(AF_INET,SOCK_DGRAM,IPPROTO_UDP);
    if (hSocket == INVALID_SOCKET)
      return 0;
    // initialize localhost IP  
    GetComputerName(hn,&hs);
    if (!GetHostAddr(hn,Port,&la))
      return 0;
    // bind on user designated Port
    if (bind(hSocket,&la,sizeof(SOCKADDR)))
      return 0; 
    // start rx thread
    rxThread = CreateThread(NULL,0,&ReceiveDatagrams,NULL,0,0);
    return lp; }

This is for UDP connections, TCP is a little different but no less complex.
