A `GtkBuilderScope` implementation for the C language.
`GtkBuilderCScope` instances use symbols explicitly added to builder with prior calls to [
[email protected]_callback_symbol]. If developers want to do that, they are encouraged to create their own scopes for that
purpose.
In the case that symbols are not explicitly added; GTK will uses `GModule`’s introspective features (by opening the module
null) to look at the application’s symbol table. From here it tries to match the signal function names
given in the interface description with symbols in the application.
Note that unless [[email protected]_callback_symbol] is called for all signal callbacks which are referenced by the loaded
XML, this functionality will require that `GModule` be supported on the platform.
