>I want to write a function that pops up a window in SunView.
I have had the same problem for a long time till I discovered that you do
not need another window_loop or window_main_loop. You start a program your
base frame and window _main_loop and later you could call a function that
does window_create. Set up your window with panels or whatever and just
call window_set(popup_window, WIN_SHOW, TRUE, 0);
This works just fine and is non-blocking. I also noticed that with two
window_main_loops, the notifier gives an error message, "Invalid argument"
but does nothing much else, at least as far as I could see.

Subject: Re: Popping up an independent window in SunView (2)
I am in the process of writing a multi window application. In order to
create new windows I have used the call
win_insert(windowfd);
where the windowfd is obtained by
window_get(window,WIN_FD);
This also allows the program to call other window management commands such as
wmgr_close(windowfd,rootfd);
wmgr_open(windowfd,rootfd);
wmgr_move(windowfd,rootfd);
wmgr_stretch(windowfd,rootfd);
wmgr_top(windowfd,rootfd);
wmgr_bottom(windowfd,rootfd);
wmgr_refreshwindow(windowfd);
where move and stretch interact with the user. rootfd is obtained from
parent = (char *) getenv("WINDOW_PARENT");
rootfd = open(parent, 0);
For more information see;

In cayuga.cs.rochester.edu:public/latex-style is rscsencode.shar. My
ex-archive server offered this encoding option for requests. It is said
to be more cautious than uuencode because it only uses the characters
[A-Za-z0-9+-]. I cannot vouch for it being much better than uuencode, but
I cannot imagine a Bitnet node mangling these characters. Maybe an
uppercase only machine? :-)

One hint for using uuencode/uudecode across BITNET - be sure to use
"uurepair" (sorry - can't remember the source) to pad all the lines of the
received uuencoded file out to the proper length.
BITNET truncates all the trailing blanks...

Subject: Re: rsh woes
doug at icase.edu installed a namedaemon and now people can't do rsh from
other networks to his system.
We have a fairly complex setup -- two closely integrated networks, each
with independent YP, plus Vaxen and miscellany. We had a rash of similar
rsh problems. It turned out that it wasn't entirely obvious what
named/ypserv was going to use for a hostname on incoming connections. Try
using nslookup to reverse-map the internet address of the site from which
the rsh is coming. e.g.
prompt>nslookup
server sunset.....
> set type=ptr
> 16.64.97.128.in-addr.arpa. (substitute internet adr here, backwards)
and it gives you the hostname that you need in .rhosts.
Another problem occurs if the other site has two Ethernet boards, e.g. has
workstations on ie0 and the backbone Ethernet on ie1. Normally you will
put the "real" hostname on ie0 and a substitute (e.g.
malibu2.pic.ucla.edu) on ie1; however, hosts on the backbone think rsh's
are coming from the substitute name. I hope one or the other of these
ideas helps.

First, the SunView manual says that WIN_FONT only affect panels and text
subwindows (Chapter 4). Second, pf_default() doesn't take an argument,
since it opens the system default font; use pf_open(font_name_here)
instead. However, in SunOS 3.5, I find that WIN_FONT only affects panels,
not text subwindows. One workaround is to
setenv DEFAULT_FONT your_font_here
What's the deal with text subwindows and fonts? What am I missing?

Subject: /dev/ttya operations on 3/80 server crash SunOS 4.0
Opening, closing and reopening /dev/ttya causes our Sun 3/280S server, and
another 4/280 server on the Purdue campus, both running SunOS 4.0, to
crash. The crash is described on the console with the messages:
staff vmunix: trap address 0x8, pid 240, pc = f029380,
sr = 2004, stkfmt b, context 3
staff vmunix: Bus Error Reg 80<INVALID>
Investigation of the dump produced by this crash shows that the bus error
is occurring in the following instruction of the prologue of stropen() in
/usr/src/sys/os/str_io.c.
register struct vnode *vp = *vpp;
Here is a simple test program that will exploit the bug:
#include <stdio.h>
#include <sys/file.h>
int fd;
main(argc, argv)
{
opn();
if (close(fd) < 0) {
perror("close");
exit(1);
}
opn();
exit(0);
}
opn()
{
if ((fd = open("/dev/ttya", O_RDWR)) < 0) {
perror("open /dev/ttya");
exit(1);
}
}
/dev/ttya and /dev/console are the same physical device. On occasion,
syslogd will cause the same crash when it is given a SIGHUP. When syslogd
receives a SIGHUP it closes /dev/console and then reopens it in the
process of rescanning /etc/syslog.conf.
Kermit will also cause the crash by using its "set line /dev/ttya" command
in two, separate invocations of Kermit.

Subject: 386i c compiler bug
In my previous posting regarding the compiler losing an extern declaration
in a situation similar to the following:
#include "foo.h"
main ()
{
extern foo_type f(); /* foo_type is a pointer to a struct */
foo_type a, b, c, d;
a = f ();
b = f ();
{
c = f();
}
d = f ();
}
I mentioned that this was a simplification of the problem, which involved
a good deal more code. It is actually an X11 program, about 400 lines
long, with a number of include files. I appreciate the responses I have
gotten; I should have thought to try the simple case myself on the 386i,
even thought I knew it had worked elsewhere. The sample (foo.c) I included
indeed works fine on the 386i. I was hoping someone had some insight to
the problem based on prior experience, familiarity with the Sun internals,
or whatever. Looking at the preprocessor output has given me no clues,
either. If someone wouldnt mind doing a test compile on a Sun 3 or 4
(pref. 4.0, but whatever), I would appreciate it. I can email the source;
obviously you need to have X11 (r2) up already. Again, thanks to those who
have responded.

Is it possible to access a remote tape drive without 'rlogin'ing to the
remote machine?
Here is the setup: A Sun 3/50 is a diskless node on our server, a 3/260.
What I would like to do is access the tape drive without having to rlogin
to the server. I have tried using MAKEDEV, etc to create a suitable
device but to no avail. Is this possible?
Thanks in advance,

Subject: /var/spool/lpd/err files
We're using TranScript 1.1 on SunOS 4.0 to drive a DEC ScriptPrinter.
The TransScript documentation (and the SunOS documentation) claim that
error messages get put into the file specified by ``lf'' in the printcap
entry. This is, in part, true: the output from psbanner gets put there.
However, there's another file that gets created in the spool directory,
labeled errABCDE where ABCDE is probably a process number. This file
contains the useful error messages from the PostScript printer (i.e. all
the messages that tell you why your print didn't come out of the printer).
I can find no incantation that makes these messages go to the log file.
Has anyone else run into this problem? Any clues? Suggestions? I will
summerize responses if there is interest.

Subject: lint and SPARC
We just went to SunOS 4.0 and installed a Sun 4 upgrade and something's
really irritating me. It is no longer possible to do some things without
provoking lint messages. In particular, using varargs stuff with pointer
arguments (as in the man page example) produces "pointer alignment"
warnings, and if one uses the lint library definitions for the malloc
family the compiler freaks with a ton of error messages since the proper
type for these things (unknown to lint) is now void *. Is Sun planning to
do anything about this? As far as I'm concerned, it makes lint virtually
unusable, unless one goes through the messages one by one to determine
which represent real problems and which are just suspicions.

Subject: opinions on configuration wanted
on the following setup: 1 sun 3/60 with 327M disk & tape drive,
4 diskless sun 3/50 clients.
the system will start with just the 3/60 and one 3/50, but will grow to
include 3 more 3/50s. all systems will initially have only 4M of memory.
i know this is marginal -- i'll buy more from the aftermarket, hopefully.
when the system reaches 5 nodes, at most 2 of the 3/50s are likely to be
doing any serious crunching at one time.
i'm familiar with the performance of a 3/280 serving a bunch of clients,
but does anyone have experience with a 3/60 serving a couple clients? the
3/60 itself will be used for some serious crunching, as well... (gnu +
compile/links).
how is the 327M disk? is it an RLL or ERLL unit? is it very loud? i
think that 327M is marginal for a 5 node network, and would consider
getting local swap disk shoeboxes when more 3/50s get added.
any opinions appreciated! please use email -- the PO for this stuff will
probably be put in very shortly.
also.. any comments on OCLI screens? i've used them and they are much
nicer -- but are they worth $1000 more?
thanks...
