Does 'code from 4.2 BSD' mean snippets of actual kernel code or more like examples of BSD-specific syscalls and networking (socket(), select()) and such? In the latter case you could see if you can still get a copy of the old (1986) book 'C Programming in the Berkeley Unix Environment' which was pretty much filled with BSD specific stuff and how that was perhaps done in attributing the correct parties: https://www.abebooks.com/9780131097605/Programming-Berkeley-Unix-Environment-Horspool-0131097601/plp Unfortunately my copy got lost over some moves, so I no longer have one to look it up... Bye, Arno.
