Abstract

DBUS is a Free/Open Source software interprocess communications (IPC) mechanism that is in widespread use by open source desktop software today. It is part of the freedesktop.org project and used in a wide range of applications. Examples include hotplug notifications on Linux, desktop search queries in strigi and as the primary means of IPC in KDE 4.
