Message-ID: <9701071955.AA05252@oldp.nmsu.edu> (raw)
I've looked at this for a little while and these diffs seems to work
for me on
SunOS charon 5.5 Generic sun4u sparc SUNW,Ultra-1
when compiled with c89 and without -lbsd or -lreadline.
There seem to be two things to get right: the behaviour on interrupts
with and without a handler. I think this does the right thing, but rc
signals are pretty much Greek to me.
Regards,
Alan
