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. + * + * Communication with the child process:\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.
