Introduction:
- Server side
- succesfully connected with the client
- regular traffic of information
- the client close his socket
  -    ::shutdown(s->socket, SD_SEND);
        if (::closesocket(s->socket) == 0)
        {
          if (::WSACleanup() != 0)
            myWSAErrorCode(::WSAGetLastError());
        }
        else
            myWSAErrorCode(::WSAGetLastError());
- on the server side the reading loop (i've tested both method)
   1) avail = -1;
       bytes = ::ioctlsocket(sock, FIONREAD, &avail);
   2)  avail = -1;
        FD_ZERO(&read_fd);
        FD_SET(s->socket, &read_fd);
        if (::select(s->socket+1, &read_fd, NULL, NULL, NULL) !=
SOCKET_ERROR)
        {
          ret = ::ioctlsocket(s->socket, FIONREAD, &avail);
          if (ret == 0)
            return avail;
        }
        return -1;
Problem:
- select() return immediately (also if timeout parameter is NULL), returning
1 (no error)
  but this socket should be closed/invalid
- ioctlsocket() return 0 and set avail to 0
If i call recv() the function return SOCKET_ERROR (correct) but i've to read
data in a static buffer and i wish to allocate memory dinamically knowing
the exact size

Thanks in advance
