Vanguard (microkernel)
Vanguard was an experimental microkernel developed at Apple Computer in the early 1990s. Based on the V-System, Vanguard introduced standardized object identifiers and a unique "message chaining" system for improved performance. Vanguard was not used in any of Apple's commercial products, and development ended in 1997 when Apple's research group (ATG) was dismantled.
==Basic concepts==
Vanguard was generally very similar to the V-System, but added support for true object oriented programming of the operating system. This meant that kernel and server interfaces were exported as objects, which could be ''inherited'' and extended in new code. This change has no real effect on the system itself, it is primarily a change in the source code that makes programming easier.
For instance, Vanguard had an I/O class which was supported by a number of different servers, networking and file servers for instance, which new applications could interact with by importing the I/O interface and calling methods. This also made writing new servers much easier, both because they had a standard to program to, as well as being able to share code more easily.
