Or anything else that uses getlogin(), as who and ftp (for the default
login name) do. The latter seems to have been fixed in the ftp I just
tried, at least to where it will use getpwnam() rather than just use
"nobody", but "who am i" just came back with "turing.cs.rpi.edu! [...]".
(Sun4, SunOS 4.0.3, by the way.)
getlogin() definitely makes my Top 10 Most Hated C Calls list. A
rather odd little list. The calls themselves are of course not really
evil. Maybe I should change the title of the list, to something like
"Top 10 Most Abused [on purpose or accidentally] C Calls" or such.
