- <para>The <function>sd_bus_message_appendv()</function> is equivalent to
- the function <function>sd_bus_message_append()</function>,

- a variable number of arguments. This function does not call the
- <function>va_end()</function> macro. Because it invokes the
- <function>va_arg()</function> macro, the value of ap
