How much [of MacOSX] C, and how much is
Objective-C?
Since it has a BSD kernel underneath, I'm guessing that all of the OS
proper is written in C and that all the Apple stuff on top is written
in Objective-Cish.
It does not have a BSD kernel underneath. It uses the Mach
Microkernel. It has a BSD layer on top of that.
Which causes all kinds of "fun" for developers whose code has to be
aware of system details like signal handling. I remember the SBCL folks
doing some cursing about it ;-)
Kind regards,
Alex.
