Description:
deprecated library for D-Bus IPC (API documentation)
D-Bus is a message bus, used for sending messages between applications. Conceptually, it fits somewhere in between raw sockets and CORBA in terms of complexity. . This package provides the HTML documentation for dbus-glib, a deprecated GLib-based D-Bus library. New code should use GDBus, part of GLib, instead. . See the dbus description for more information about D-Bus in general.
