+ * g_settings_new_full:
+ * @schema: a #GSettingsSchema
+ * @backend: a #GSettingsBackend
+ * @path: the path to use
+ * @returns: a new #GSettings object
+ *
+ * Creates a new #GSettings object with a given schema, backend and
+ * path.
+ *
+ * It should be extremely rare that you ever want to use this function.
+ * It is made available for advanced use-cases (such as plugin systems
+ * that want to provide access to schemas loaded from custom locations,
+ * etc).
+ *
+ * At the most basic level, a #GSettings object is a pure composition of
+ * 4 things: a #GSettingsSchema, a #GSettingsBackend, a path within that
+ * backend, and a #GMainContext to which signals are dispatched.
+ *
+ * This constructor therefore gives you full control over constructing
+ * #GSettings instances.  The first 4 parameters are given directly as
+ * @schema, @backend and @path, and the main context is taken from the
+ * thread-default (as per g_settings_new()).
+ *
+ * Since: 2.32
