|

* @Title: GIRegisteredTypeInfo
|
|
*
|
|
* GIRegisteredTypeInfo represents an entity with a GType associated. Could
|
|
* be either a #GIEnumInfo, #GIInterfaceInfo, #GIObjectInfo, #GIStructInfo or a
|
|
* #GIUnionInfo.
|
|
*
|
|
* A registered type info struct has a name and a type function.
|
|
* To get the name call g_registered_type_info_get_type_name().
|
|
* Most users want to call g_registered_type_info_get_g_type() and don't worry
|
|
* about the rest of the details.
