I'm attempting to get a program which uses stdio to work when
undumped on a Sun-3, running SunOS-3.2. I'm using the version of undump
which comes on the U. of W. TeX tape, by Spencer Thomas, with various
hackings by der Mouse and by myself to make it work on a Sun-3. I'm
reasonably sure there is nothing wrong with undump since undumped TeX
works.
The problem is, all my printf calls seem to get ignored. I can see
printf get called with the proper arguments using dbx, but nothing is
printed. Since the stdio library maintains its own set of buffers, I can
see all sorts of way printf might get confused by undump. Is it possible
to use printf in an undumped program? Any special tricks I need to make it
work? Closing all open files before dumping and using fdopen to get
std{in,out,err} back when it starts up again is the next thing I'm going to
try. Even if it works I'd like to hear if other people think this is
portable (not that I'm sure anything having to do with undump can really be
considered portable), hence this note.
