Detailed Description
This class implements a very simple IPC mechanism for KDE.You can send a message of a predefined type to either a specific application, or to all KDE application on the current display. The message can carry one integer of data.
KIPC is mainly used in KDE for sending "Change Messages", i.e. a message to all KDE apps that a certain setting (the font, for example) has changed. For anything more complex it is recommended to use DCOP -- the Desktop Communications Protocol.
Messages with id code < 32 are called "System Messages". These are directly handled by KApplication. Examples are: PaletteChanged and StyleChanged. Messages with id code >= 32 are user messages. KApplication emits the signal kipcMessage(id,arg) for each user message it receives.
KIPC is implemented using X11 ClientMessage events.
