Introduction¶
An at least basic knowledge of D-Bus and its specification is required for working with this library.

Features¶
Supported authentication mechanisms¶
EXTERNAL
DBUS_COOKIE_SHA1
ANONYMOUS
Supported transports¶
Unix Domain Sockets
TCP Sockets
Nonce-authenticated TCP Sockets
Unix file descriptor passing¶
If supported by the actual transport, file descriptors or file objects with a
fileno() method can be used as arguments for parameters with the
D-Bus type code 'h'. The file descriptors should be duplicated
before passing them as arguments. For convinience the dcar.UnixFD class
should be used.
