// ****************************************************************************
// Method: SocketConnection::Flush
//
// Purpose:
// Writes the entire contents of the connection's buffer onto the
// socket file descriptor in chunks. It then clears the buffer.
//
//
// Programmer: Brad Whitlock
// Creation: Tue Aug 29 12:17:37 PDT 2000
//
// Modifications:
// Brad Whitlock, Tue Mar 26 13:29:20 PST 2002
// Made it use socket functions so it is more portable.
//
// Brad Whitlock, Thu Jan 25 18:42:50 PST 2007
// I made it use MSG_NOSIGNAL so we don't get a signal in the event that
// we can't write to the socket.
//
// Eric Brugger, Tue Mar 13 09:18:48 PDT 2007
// I made the use of MSG_NOSIGNAL conditional on its definition.
