setlogin () -- what does it do?

[Scott Ballantyne]

I have been looking at the login.c source from
bsd-sources/usr.bin/login on uunet, and it uses what is apparently a
new system call: setlogin (username). Can someone tell me what this is
supposed to do, or aim me at the man page?

Also, is it possible to use this login.c to replace the login program
on SunOS 4.1.1?

Thanks,
sdb
