+ * @call: a #RestProxycall
+ * @error_out: a #GError or %NULL
+ *
+ * Synchronously invokes @call. After this function has returned,
+ * rest_proxy_call_get_payload() will return the result of this call.
+ *
+ * Note that this will block an undefined amount of time, so
+ * rest_proxy_call_invoke_async() is generally recommended.

+ * Returns: %TRUE on success, %FALSE if a failure occurred,
+ *   in which case @error_out will be set.
