- *
- * NX_SIGNAL_ENABLE:  A signal handler will have to be installed by
- *                    the library, so that it can be intercepted by
- *                    the proxy.
- *
- * NX_SIGNAL_DISABLE: The signal will be handled by the caller and,
- *                    eventually, forwarded to the proxy by calling
- *                    NXTransSignal() explicitly.
- *
- * NX_SIGNAL_RAISE:   The signal must be handled now, as if it had
- *                    been delivered by the operating system. This
- *                    function can be called by the agent with the
- *                    purpose of propagating a signal to the proxy.
- *
- * NX_SIGNAL_FORWARD: A signal handler will have to be installed by
- *                    the library but the library will have to call
- *                    the original signal handler when the signal
- *                    is received.
- *
- * As a rule of thumb, agents should let the proxy handle SIGUSR1
- * and SIGUSR2, used for producing the NX protocol statistics, and
- * SIGHUP, used for disconnecting the NX transport.
- *
- * The following signals are blocked by default upon creation of the
- * NX transport:
- *
- * SIGCHLD    These signals should be always put under the control
- * SIGUSR1    of the proxy. If agents are intercepting them, agents
- * SIGUSR2    should later call NXTransSignal(..., NX_SIGNAL_RAISE)
- * SIGHUP     to forward the signal to the proxy. As an alternative
- *            they can specify a NX_SIGNAL_FORWARD action, so they,
- *            in turn, can be notified about the signal. This can
- *            be especially useful for SIGCHLD.
- *
- * SIGINT     These signals should be intercepted by agents. Agents
- * SIGTERM    should ensure that NXTransDestroy() is called before
- *            exiting, to give the proxy a chance to shut down the
- *            NX transport.
- *
- * SIGPIPE    This signal is blocked by the proxy, but not used to
- *            implement any functionality. It can be handled by the
- *            NX agent without affecting the proxy.
- *
- * SIGALRM    This is now used by the proxy and agents should not
- *            redefine it. Agents can use the signal to implement
- *            their own timers but should not interleave calls to
- *            the NX transport and should restore the old handler
- *            when the timeout is raised.
- *
- * SIGVTALRM  These signals are not used but may be used in future
- * SIGWINCH   versions of the library.
- * SIGIO
- * SIGTSTP
- * SIGTTIN
- * SIGTTOU
- *
- * By calling NXTransSignal(..., NX_SIGNAL_DISABLE) nxcomp will res-
- * tore the signal handler that was saved at the time the proxy hand-
- * ler was installed. This means that you should call the function
- * just after the XOpenDisplay() or any other function used to init-
- * ialize the NX transport.

- * The data can be NX_STATISTICS_PARTIAL or NX_STATISTICS_TOTAL. The
- * agent can refer to the value by using the  NXStatisticsPartial and
- * NXStatisticsTotal constants defined in NXvars.h.

- * used for the subsequent I/O. The type parameter not only tells to
- * the proxy the remote port where the channel has to be connected,
- * but also gives a hint about the type of data that will be carried
- * by the channel, so that the proxy can try to optimize the traffic
- * on the proxy link.
- *
- * NX_CHANNEL_X:     The channel will carry X traffic and it
- *                   will be connected to the remote X display.
- *
- * NX_CHANNEL_CUPS:  The channel will carry CUPS/IPP protocol.
- *
- * NX_CHANNEL_SMB:   The channel will carry SMB/CIFS protocol.
- *
- * NX_CHANNEL_MEDIA: The channel will transport audio or other
- *                   multimedia data.
- *
- * NX_CHANNEL_HTTP:  The channel will carry HTTP protocol.
- *
- * NX_CHANNEL_FONT:  The channel will forward a X font server
- *                   connection.
- *
- * Only a proxy running at the NX server/X client side will be able
- * to create a X, CUPS, SMB, MEDIA and HTTP channel. A proxy running
- * at the NX client/X server side can create font server connections.
- * The channel creation will also fail if the remote end has not been
- * set up to forward the connection.
- *
- * To create a new channel the agent will have to set up a socketpair
- * and pass to the proxy one of the socket descriptors.
- *
- * Example:
- *
- * #include <sys/types.h>
- * #include <sys/socket.h>
- *
- * int fds[2];
- *
- * if (socketpair(PF_LOCAL, SOCK_STREAM, 0, fds) < 0)
- * {
- *   ...
- * }
- * else
- * {
- *   //
- *   // Use fds[0] locally and let the
- *   // proxy use fds[1].
- *   //
- *
- *   if (NXTransChannel(NX_FD_ANY, fds[1], NX_CHANNEL_X) <= 0)
- *   {
- *     ...
- *   }
- *
- *   //
- *   // The agent can now use fds[0] in
- *   // read(), write() and select()
- *   // system calls.
- *   //
- *
- *   ...
- * }
- *
- * Note that all the I/O on the descriptor should be non-blocking, to
- * give a chance to the NX transport to run in the background and handle
- * the data that will be fed to the agent's side of the socketpair. This
- * will happen automatically, as long as the agent uses the XSelect()
- * version of the select() function (as it is normal whenever performing
- * Xlib I/O). In all the other cases, like presumably in the agent's main
- * loop, the agent will have to loop through NXTransPrepare(), NXTrans-
- * Select() and NXTransExecute() functions explicitly, adding to the sets
- * the descriptors that are awaited by the agent. Please check the imple-
- * mentation of _XSelect() in nx-X11/lib/X11/XlibInt.c for an example.
