-/**
- * Child process invocation, monitoring and control.
- *
- * @sect General usage and features
- *
- *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 KProcIO
- *
- *Basically, this class distinguishes three different ways of running
- *child processes:
- *
- *@li KProcess::DontCare -- The child process is invoked and both the child
- *process and the parent process continue concurrently.
- *
- *Starting a DontCare child process means that the application is
- *not interested in any notification to determine whether the
- *child process has already exited or not.
- *
- *@li KProcess::NotifyOnExit -- The child process is invoked and both the
- *child and the parent process run concurrently.
- *
- *When the child process exits, the KProcess instance
- *corresponding to it emits the Qt signal @ref 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 KProcess objects gets destructed, the child
- *process will be killed if it is still running!
- *This means in particular, that you cannot use a KProcess on the stack
- *with KProcess::NotifyOnExit.
- *
- *@li KProcess::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.)
- *
- *KProcess 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:
- *<pre>
- *KProcess *proc = new KProcess;
- *
- **proc << "my_executable";
- **proc << "These" << "are" << "the" << "command" << "line" << "args";
- *QApplication::connect(proc, SIGNAL(processExited(KProcess *)),
- * pointer_to_my_object, SLOT(my_objects_slot(KProcess *)));
- *proc->start();
- *</pre>
- *
- *This will start "my_executable" with the commandline arguments "These"...
- *
- *When the child process exits, the respective Qt signal will be emitted.
- *
- *@sect Communication with the child process
- *
- *KProcess 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 bool @ref writeStdin(char *buffer, int buflen);
- *@li -- Transmit data to the child process's stdin.
- *
- *@li bool @ref closeStdin();
- *@li -- Closes the child process's stdin (which causes it to see an feof(stdin)).
- *Returns false if you try to close stdin for a process that has been started
- *without a communication channel to stdin.
- *
- *@li bool @ref closeStdout();
- *@li -- Closes the child process's stdout.
- *Returns false if you try to close stdout for a process that has been started
- *without a communication channel to stdout.
- *
- *@li bool @ref closeStderr();
- *@li -- Closes the child process's stderr.
- *Returns false if you try to close stderr for a process that has been started
- *without a communication channel to stderr.
- *
- *
- *@sect QT signals:
- *
- *@li void @ref receivedStdout(KProcess *proc, char *buffer, int buflen);
- *@li void @ref receivedStderr(KProcess *proc, char *buffer, int buflen);
- *@li -- Indicates that new data has arrived from either the
- *child process's stdout or stderr.
- *
- *@li void @ref wroteStdin(KProcess *proc);
- *@li -- Indicates that all data that has been sent to the child process
- *by a prior call to @ref writeStdin() has actually been transmitted to the
- *client .
- *
