## Detailed Description

A simple value union that lets you access bytes as if they were various types; useful when dealing with basic types via void pointers and varargs.

This union also contains a pointer member (which can be used to retrieve a string from dbus_message_iter_get_basic(), for instance), so on future platforms it could conceivably be larger than 8 bytes.
