D-bus

D-Bus

D-Bus is an inter-process communication (IPC) open-source system for software applications to communicate with one another. Heavily influenced by KDE 2–3's DCOP system, D-Bus has replaced DCOP in the KDE 4 release. An implementation of D-Bus supports most POSIX operating systems, and a port for Windows exists. It is used by Qt 4 and GNOME. In GNOME it has gradually replaced most parts of the earlier Bonobo mechanism.
