[TUHS] UNIX V6 line 3973: Is it really a typo?

[Brian S Walden]

See the December 2002 discussion threads "V6: 50 bugs tape"
and "Patches to improve 6th Edition" in the archive
(http://minnie.tuhs.org/pipermail/tuhs/2002-December/date.html)
While not specifically mentioned in those mails it is part
of the 50 bugs tape -- you'll want to extract usr/sys/v6unix/* from
http://www.tuhs.org/Archive/Applications/Spencer_Tapes/unsw3.tar.gz
and you'll see it fixed in usr/sys/v6unix/updat/ken/sig.c

hi Hellwig,

Thanks for pointing out.

I was viewing actually the V6's source while I had thought it's V7.

Thanks &
Regards,

Qinglai

it was changed in V7 to p_pri (file sig.c, lines 64/65).

hi all,

It's stated in Lion's book chapter 13.13 that at line 3973, i.e. the
function psignal, there is a typo where the p_stat should be p_pri.

Is there anyone can confirm it?

If it's really a bug, why it remains p_stat in UNIX V7?

Thanks in advance

Qinglai
