#### Description

    final class Gio.IOModule : GObject.TypeModule
      implements GObject.TypePlugin {
      /* No available fields */
    }

Provides an interface and default functions for loading and unloading modules. This is used internally to make GIO extensible, but can also be used by others to implement module loading.

Available since: 2.0

##### Methods inherited from GTypeModule (7)

###### g_type_module_add_interface

Registers an additional interface for a type, whose interface lives in the given type plugin. If the interface was already registered for the type in this plugin, nothing will be done.

since: 2.0

###### g_type_module_register_enum

Looks up or registers an enumeration that is implemented with a particular type plugin. If a type with name `type_name` was previously registered, the `GType` identifier for the type is returned, otherwise the type is newly registered, and the resulting `GType` identifier returned.

since: 2.6

###### g_type_module_register_flags

Looks up or registers a flags type that is implemented with a particular type plugin. If a type with name `type_name` was previously registered, the `GType` identifier for the type is returned, otherwise the type is newly registered, and the resulting `GType` identifier returned.

since: 2.6

###### g_type_module_register_type

Looks up or registers a type that is implemented with a particular type plugin. If a type with name `type_name` was previously registered, the `GType` identifier for the type is returned, otherwise the type is newly registered, and the resulting `GType` identifier returned.

since: 2.0

###### g_type_module_set_name

Sets the name for a `GTypeModule`.

since: 2.0

###### g_type_module_unuse

Decreases the use count of a `GTypeModule` by one. If the result is zero, the module will be unloaded. (However, the `GTypeModule` will not be freed, and types associated with the `GTypeModule` are not unregistered. Once a `GTypeModule` is initialized, it must exist forever.)

since: 2.0

###### g_type_module_use

Increases the use count of a `GTypeModule` by one. If the use count was zero before, the plugin will be loaded. If loading the plugin fails, the use count is reset to its prior value.

since: 2.0

##### Methods inherited from GObject (43)

Please see GObject for a full list of methods.

##### Methods inherited from GTypePlugin (4)

###### g_type_plugin_complete_interface_info

Calls the `complete_interface_info` function from the `GTypePluginClass` of `plugin`. There should be no need to use this function outside of the GObject type system itself.

since: 2.0

###### g_type_plugin_complete_type_info

Calls the `complete_type_info` function from the `GTypePluginClass` of `plugin`. There should be no need to use this function outside of the GObject type system itself.

since: 2.0

###### g_type_plugin_unuse

Calls the `unuse_plugin` function from the `GTypePluginClass` of `plugin`. There should be no need to use this function outside of the GObject type system itself.

since: 2.0

###### g_type_plugin_use

Calls the `use_plugin` function from the `GTypePluginClass` of `plugin`. There should be no need to use this function outside of the GObject type system itself.

since: 2.0

#### Signals

##### Signals inherited from GObject (1)

###### GObject::notify

The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
