<title>GIRepositoryBaseInfo</title>
<p>GIBaseInfo is the common base struct of all other *Info structs
accessible through the #GIRepository API.
All other structs can be casted to a #GIBaseInfo, for instance:
<example>
<title>Casting a #GIFunctionInfo to #GIBaseInfo</title>
<programlisting>
GIFunctionInfo *function_info = ...;
GIBaseInfo *info = (GIBaseInfo*)function_info;
</programlisting>
</example>
Most #GIRepository APIs returning a #GIBaseInfo 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>
