53 * Routines for working with D-Bus addresses. A D-Bus address is a string
54 * like "unix:tmpdir=/tmp/my-app-name". The exact format of addresses
55 * is explained in detail in the <link linkend="http://dbus.freedesktop.org/doc/dbus-specification.html#addresses">D-Bus specification</link>.

68 * This doesn't check if @string is actually supported by #GDBusServer
69 * or #GDBusConnection - use g_dbus_is_supported_address() to do more
