GTypeModule Type Loading Modules #GTypeModule provides a simple implementation of the #GTypePlugin interface. The model of #GTypeModule is a dynamically loaded module which implements some number of types and interface implementations. When the module is loaded, it registerse its types and interfaces using g_type_module_register_type() and g_type_module_add_interface(). As long as any instances of these types and interface implementations are in use, the module is kept loaded. When the types and interfaces are gone, the module may be unloaded. If the types and interfaces become used again, the module will be reloaded. Keeping track of whether the module should be loaded or not is done by using a use count - it starts at zero, and whenever it is greater than zero, the module is loaded. The use count is maintained internally by the type system, but also can be explicitely controlled by g_type_module_use() and g_type_module_unuse(). Typically, when loading a module for the first type, g_type_module_use() will be used to load it so that it can initialize its types. At some later point, when the module no longer needs to be loaded except for the type implementations it contains, g_type_module_unuse() is called. #GTypeModule does not actually provide any implementation of module loading and unloading. To create a particular module type you must derive from #GTypeModule and implement the load and unload functions in #GTypeModuleClass. #GTypePlugin The abstract type loader interface. #GModule Portable mechanism for dynamically loaded modules. @parent_instance: @use_count: @type_infos: @interface_infos: @name: @module: @Returns: @module: @module: @name: @module: @parent_type: @type_name: @type_info: @flags: @Returns: @module: @instance_type: @interface_type: @interface_info:
