[comp.sys.hp] Help with Pseudo Terminals

wehr@fmeed1.UUCP (Bruce Wehr) (01/09/90)

If I understand what pseudo-terminals do correctly, then we have an
application that could benefit greatly from using them.  However, I'm
not very familiar with how to use them.

We're using HP-UX 6.5 on an HP9000/370.  The man entry pty(7) has got us
off the ground, but I could use something more tutorial-like (there are
some things happening that I don't quite understand - like our process
becoming defunct and ignoring signal 9 - and monitor shows it has pty's
open).  Also, what services does the ptydaemon provide, and how does one
employ it (I've read TFM, and found no reference to this daemon)?

Any help, *help, or **help would be greatly appreciated.

Follow-ups are being directed to me.  Anyone interested in a summary of
responses can send me mail.  If you *must* post, please post to
comp.sys.hp.

Forget about ptydaemon. You need a special library (which is not 
provided) to use it. It is also not documented anywhere.

I can give you example code that uses pty's, if you want it.
