## Description

dbus-glib's built-in factory functions for specialized GTypes need to do a fair amount of parsing on their arguments, so these macros are provided to avoid that. Each macro expands to a call to a function which caches the GType, so it only ever has to call into dbus-glib once.

`tp_dbus_specialized_value_slice_new()` is also provided.

<tp:docstring xmlns="http://www.w3.org/1999/xhtml"> <p>Part of a message's content.
