I know what the entry point(s) to ioctl are (I've seen
enough drivers but where are the fcntl entry points?
There is sort of an overlap there. Will a fcntl cause
a call to dev_ioctl?

Well, it's not supposed to -- fcntl() was introduced specifically
to play with the file table entries, which is something the device
driver is not supposed to know (or care) about.

How 'bout we switch to normal regular expressions and say something like:
(u.*[nx]|[rn].*x|ix)
That gets most of 'em, and maybe a few that haven't been invented yet.
Or perhaps

Or maybe that should that be

Probably get a false positive with that one, though. :-)

Yup, I'd forgotten that little Tale of Terror from 4.0 development days.
If you have to do something like
if (foo->bar->bletch == mem_rop) {
/*
* Do special memory pixrect stuff
*/
} else {
/*
* Do other pixrect stuff
*/
}
this comes into play (i.e., it's not *any* reference by name that causes
problems, it's references that actually care about the address of the
function as something other than the target of a jump).

I have to start a session programaticly on a terminal, the terminal
is local to my machine, but for reasons that make no difference I am forced
to start the session for them. (meaning that instead of letting someone log
into a script or anything else, the data entry screen has to be there for them).
Unfortunately I can not make the data entry program open the dev I want to
use because it is an existing package.
I am running SCO XENIX on everex 286 systems, version 2.2.3.
Please help me! Thanks in advance Dave

Try putting the statement ".nr PS 12" at the very beginning of
your program. You may need to include "gsize 12" in your .EQN
definitions if you're using eqn.

That's true, .sz does a temporary size change, respectively every
call to .pp or similar macros resets the point size.

There is. The number register pp defines the pointsize used throughout
the entire document; the macros pp, lp and the like set the pointsize
to the value of that number register. So the first thing you put in
Your paper is '.nr pp 12' and everything should work fine.

I had a similar kind of a problem on a Pyramid running ATT Sys 5, having
csh as the base shell. I have a Bourne shell script that is started up
from my .login, which runs a clock at the top corner of my tty. When I
log out, however, the process remains active even though there is no
actual device to output to. I tried in the script to 'trap' the signals,
but they are not received on logout.
The suggestion to:
a) set setpgrp() is slightly a pain in a shell script.
b) modify /bin/login (?) is impossible for me.
Right now, in my .logout I do a ps, and use awk to get the pid so that
I can explicitly kill the process. However, I wish the script would
directly get the signal when I logout and expire!

I've checked the list of common questions, and haven't seen this one, so
I guess it is legal.. :)
Is there some sort of description of/introduction to the socket-concept
available (either on a file somewhere, or on paper)?? I've tried to get by
on the man pages, but either I'm not looking the right places, or the info
there is a bit thin (The man pages, I think, are generally most useful if
you know the material beforehand).
I'd be grateful for any references.

The current versions of Unix kermit have a make for 'att3bx', which is
used to get the right directory for setting up lockfiles.

To: info-unix at sem.brl.mil
Hello,
I currently work part time for a relatively small software development
company called XCEL-Soft. We are based in Toronto, and our major
product is a retail banking system that runs on a UNIX System V
platform.
Right now, we are in the midst of designing an 'Inter-Branch Banking'
facility, and we are planning to make use of a Public Data Network (X25)
to facilitate communications between branches. The software
has been developed by us, for this project, and is now being tested
on a local network.
While this poses no problems from our point of view, it is felt
by one of our major customers (A bank based in Jamaica), and by my
employer, that a private network would be more secure, and offer
better response times.
We are looking at a solution of porting our retail banking system
to BSD, and perhaps implementing a TCP/IP network of some kind
that would facilitate inter-branch communication. We have various
other reasons for switching to BSD, eg. the socket is a more robust
IPC mechanism than is the standard System V IPC Message Queue routines,
and our banking software relies heavily on this. But this article
is not concerned with that...
We are experienced with X25, and interfacing our banking software
to other networks. (VISA/NET in particular) .
This leaves us with a few questions, that I am sure many of the
knowledgable gurus out there could answer for us :
1) Were could we write, or call, or FTP to obtain information
concerning
a) The purchase of 4.3BSD.
b) Implementing a TCP/IP based network.
In Particular: What types of communications medium are
supported by TCP/IP.
(With our PDN solution, each branch
has a leased line to the network, is that
possible with a TCP/IP solution?)
These are broad, and rather vague questions, but any responses would
be appreciated.
All responses should be directed to :

Hi everybody,
I wrote a program that deals with connectivity information of a logic
design. I took the connectivity information from a CAD tools set output.
What I want to do is to see if it is possible to "kind of" integrate
the schematic capture part of the CAD tool into my program. I do not have
the sources for the CAD system, it is a commercial tool. My program can find
some characteristics of the logic design. For some of its functions it needs
some input from the user, ie name of a part or name of a signal. Currently,
the user must type these names in, but what I am thinking of doing is to
monitor the schematic capture process from outside, ie my program, and read
the input of the user and the response of the schematic capture program.
This way the user can just use the mouse and pick a signal on the schematic
and ask for the information on that signal from the schematic capture
program, the response would be few lines of text giving the info about the
signal. This information goes to a tty subwindow of the schematic capture
frame. And I want to read this text.
I was told that I can look at the /dev/kmem and monitor the clist of that
tty window and go from there. I was wondering about some of the complications
that I am putting myself into if I go through this path. For one not
everybody has read permission to /dev/kmem, or how do I find the clist for
this tty subwindow, or if I am violating copyright if I look at the /dev/kmem
and monitor the clist.
By the way if anyone had done such a thing before, I would appreciate if
I could take a look at the program.
I am open to any other suggestions that might be applicable to this problem.
