I haven't seen nor heard on this happening on FreeBSD > [but then my travels haven't been that wide] I like C++ very much as a language. It hands me constructs which enable me to make abstractions of programming problems that are all solveable in C, be it with much more effort. With the right classes, my programs become very simple and thus less error-prone. I no longer care about buffer overruns, they simply don't occur. On the other hand, Unix is not really an object-oriented OS, so the added value of C++ (primarily data abstraction and object orientation) has little meaning. Also, performance is a consideration. C++ code tends to have more overhead. Finally, it hides a lot from you. I don't know if that's desirable in kernel code. - Peter -- Peter Korsten | peter@grendel.IAEhv.nl (UUCP) | peterk@IAEhv.nl C/C++/Perl/Java hacker
