      <doc xml:whitespace="preserve">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:
&lt;example&gt;
&lt;title&gt;Casting a #GIFunctionInfo to #GIBaseInfo&lt;/title&gt;
&lt;programlisting&gt;
GIFunctionInfo *function_info = ...;
GIBaseInfo *info = (GIBaseInfo*)function_info;
&lt;/programlisting&gt;
&lt;/example&gt;
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().
&lt;example&gt;
&lt;title&gt;Getting the Button of the Gtk typelib&lt;/title&gt;
&lt;programlisting&gt;
GIBaseInfo *button_info = g_irepository_find_by_name(NULL, "Gtk", "Button");
... use button_info ...
g_base_info_unref(button_info);
&lt;/programlisting&gt;
&lt;/example&gt;
