EExtensible *extensible
Creates an instance of all instantiable subtypes of EExtension which
target the class of extensible
. The lifetimes of these newly created
EExtension objects are bound to extensible
such that they are finalized
when extensible
is finalized.

GList * e_extensible_list_extensions (,
EExtensible *extensible);
GType extension_type
Returns a list of EExtension objects bound to extensible
whose
types are ancestors of extension_type
. For a complete list of
extension objects bound to extensible
, pass E_TYPE_EXTENSION
The list itself should be freed with g_list_free()
extensible
and should not be unreferenced.
