IIRC it's in the FAQ. Generaly speaking: - C is considered a nicer language by many hackers (C++ is a lot^Wbit bloated). - In C, it's easier to see what is going on, which is important in kernel - C++ compilers used to generate worse code and are still commonly believed to do so. - Virtual methods are actualy weaker, than an explicit function table. The function table can be exchanged runtime (IIRC it's actualy used in kerel) -- VMT can't. ------------------------------------------------------------------------------- Jan 'Bulb' Hudec <bulb@ucw.cz> -- Kernelnewbies: Help each other learn about the Linux kernel.
