COMMON MANUAL SECTIONS Manual pages are provided for most Agar object classes. Some sections are standard throughout the documentation: INHERITANCE HIERARCHY List of inherited parent classes (see AG_Object(3) for details on inheritance). EVENTS The list of events defined (or raised) by this object (see AG_Event(3) for details on events). STRUCTURE DATA List of public structure members which are safe to access directly. Multithreaded applications must use AG_ObjectLock(3) prior to accessing this data (although in some contexts, such as inside event handler routines, objects can be presumed locked; see AG_Threads(3) for de- tails).
