-/**
- * @obsolete Use KProcess and KPtyProcess instead.
- *
- * Child process invocation, monitoring and control.
- * This class works only in the application's main thread.
- *
- * <b>General usage and features:</b>\n
- *
- * This class allows a KDE application to start child processes without having
- * to worry about UN*X signal handling issues and zombie process reaping.
- *
- * @see K3ProcIO
- *
- * Basically, this class distinguishes three different ways of running
- * child processes:
- *
- * @li DontCare -- The child process is invoked and both the child
- * process and the parent process continue concurrently.
- *
- * The process is started in an own session (see setsid(2)).
- *
- * @li NotifyOnExit -- The child process is invoked and both the
- * child and the parent process run concurrently.
- *
- * When the child process exits, the K3Process instance
- * corresponding to it emits the Qt signal processExited().
- * Since this signal is @em not emitted from within a UN*X
- * signal handler, arbitrary function calls can be made.
- *
- * Be aware: When the K3Process object gets destructed, the child
- * process will be killed if it is still running!
- * This means in particular, that it usually makes no sense to use
- * a K3Process on the stack with NotifyOnExit.
- *
- * @li OwnGroup -- like NotifyOnExit, but the child process is started
- * in an own process group (and an own session, FWIW). The behavior of
- * kill() changes to killing the whole process group - this makes
- * this mode useful for implementing primitive job management. It can be
- * used to work around broken wrapper scripts that don't propagate signals
- * to the "real" program. However, use this with care, as you disturb the
- * shell's job management if your program is started from the command line.
- *
- * @li Block -- The child process starts and the parent process
- * is suspended until the child process exits. (@em Really not recommended
- * for programs with a GUI.)
- * In this mode the parent can read the child's output, but can't send it any
- * input.
- *
- * K3Process also provides several functions for determining the exit status
- * and the pid of the child process it represents.
- *
- * Furthermore it is possible to supply command-line arguments to the process
- * in a clean fashion (no null-terminated stringlists and such...)
- *
- * A small usage example:
- * \code
- * K3Process *proc = new K3Process;
- *
- * *proc << "my_executable";
- * *proc << "These" << "are" << "the" << "command" << "line" << "args";
- * QApplication::connect(proc, SIGNAL(processExited(K3Process *)),
- * pointer_to_my_object, SLOT(my_objects_slot(K3Process *)));
- * proc->start();
- * \endcode
- *
- * This will start "my_executable" with the commandline arguments "These"...
- *
- * When the child process exits, the slot will be invoked.
- *
- * <b>Communication with the child process:</b>\n
- *
- * K3Process supports communication with the child process through
- * stdin/stdout/stderr.
- *
- * The following functions are provided for getting data from the child
- * process or sending data to the child's stdin (For more information,
- * have a look at the documentation of each function):
- *
- * @li writeStdin()
- * -- Transmit data to the child process' stdin. When all data was sent, the
- * signal wroteStdin() is emitted.
- *
- * @li When data arrives at stdout or stderr, the signal receivedStdout()
- * resp. receivedStderr() is emitted.
- *
- * @li You can shut down individual communication channels with
- * closeStdin(), closeStdout(), and closeStderr(), resp.
