Hooks

A plugin can register to be called whenever an "interesting event" occurs. It does so by calling cPluginManager's AddHook() function and implementing a callback function to handle the event.

A plugin can decide whether it will let the event pass through to the rest of the plugins, or hide it from them. This is determined by the return value from the hook callback function. If the function returns false or no value, the event is propagated further. If the function returns true, the processing is stopped, no other plugin receives the notification (and possibly MCServer disables the default behavior for the event). See each hook's details to see the exact behavior.
