GIBaseInfo is the common base struct of all other *Info structs accessible through the GIRepository.Repository API. All other structs can be casted to a GIRepository.BaseInfo, for instance: <example> <title>Casting a GIRepository.FunctionInfo to GIRepository.BaseInfo</title> <programlisting> GIFunctionInfo *function_info = ...; GIBaseInfo *info = (GIBaseInfo*)function_info; </programlisting> </example> Most GIRepository.Repository APIs returning a GIRepository.BaseInfo is actually creating a new struct, in other words, g_base_info_unref() has to be called when done accessing the data. GIBaseInfos are normally accessed by calling either g_irepository_find_by_name(), g_irepository_find_by_gtype() or g_irepository_get_info().

<example> <title>Getting the Button of the Gtk typelib</title> <programlisting> GIBaseInfo *button_info = g_irepository_find_by_name(NULL, "Gtk", "Button"); ... use button_info ... g_base_info_unref(button_info); </programlisting> </example>
