C++ in the kernel

[Ali Mashtizadeh]

The Mac OS X I/O Kit has a fairly clean interface. I actually added a bit of
C++ support to my own FreeBSD Kernel a while back. If you drop exceptions
and RTTI it's fairly easy to implement. I didn't put much effort into making
any C++ API for drivers. I just used it so I could have object oriented code
in the backend of a drivers. I think it's not really worth it in most cases.

The L4 microkernel (http://l4ka.org/) has versions of its Kernel written in
C++ and they make extensive use of templates. That is probably the most
successful use of C++ in a Kernel I've seen.
