in reply to gethostbyname: What does $aliases look like?

An array of strings, I would suppose, like the system call.

Then again, Perl doesn't return an array when there's only one alias. Maybe it returns one at most?

$ perl -MData::Dumper -e'print Dumper $_ for (gethostbyname $ARGV[0])[ +0,1]' www.google.com $VAR1 = 'www.l.google.com'; $VAR1 = 'www.google.com';

Update: They are space-joined. From pp_sys.c:

PUSHs(space_join_names_mortal(hent->h_aliases));
