Since I walk in a few OS programming world... Apple has created
this 'thing' called IOKit which does implement a C++ environment
for drivers for their Mac OS X based on various pieces of *BSD.
One of the arguements put forth, is that this would allow for much
more 'flexiblity' in the future. However, it pretty much requires a
re-write of everything.
The two salient points are, in such an environment, unless there's
a 'legacy driver object', no old drivers really are usable. And two,
unless the 'open source' community takes up such a package,
there will be little 'feedback' of future drivers based on IOKit
(or equivalent...) into the community.
A couple of specific issues on C++ are, multiple inheritances,
and something really stupid, symbol name demangling....
I've been told that gcc 3, may define a name demangling
method in perpetuiti, but I'm not really knowledgeable in
those sorts of details, as I don't do much C++ programing
except when absolutely forced to.
