| |
From: Javier Martinez Canillas <javier.martinez@collabora.co.uk>
This adds AF_BUS to the socket headers and net core.
AF_BUS is a message oriented inter process communication system implemented as asocket address family. The principle features are:
- Reliable datagram based communication (all sockets are of type SOCK_SEQPACKET) - Multicast message delivery (one to many, unicast as a subset) - Strict ordering (messages are delivered to every client in the same order) - Ability to pass file descriptors - Ability to pass credentials
