I was peeking around in my /etc/master file the other day, and I noticed
these parameters...
*
* Window parameters follow
* nwindows number of windows
* nol number of obscurred pieces per system (oldefs)
* pxmapsize number of pixel map slots (see lwind/wd.c now)
* pxmemsize number of bytes of pixel memory (in virtual space)
* ndl number of display list items (used in wrastop())
*
nwindows NWINDOWS 12
nol NOL (NWINDOWS*40)
pxmemsize PXMEMSIZE (256*1024)
ndl NDL 400
Is it possible to increase NWINDOWS to something greater than 12, say
15 or 20. I changed this, removed /etc/lddrv/wind and rebooted my machine
in hopes that the number of windows would be dynamically increased
when the driver was rebound. I also did this:
for wind in 13 14 15
do
/etc/mknod /dev/w${wind} 7 ${wind}
done
When I rebooted and created 12 windows with "windy -b ksh", on the 13th
one it said:
open(): No such device or address
I pressed "SUSPD" and it said
"Out of windows... please close some windows; please wait..."
Why doesn't the window driver look at /etc/master? What good is /etc/master
if it doesn't?

Well, I thought it might be important to know who sends the error message, and
I "strings"ed the /etc/lddrv/wind, and associated files in the lddrv dir.
Then I checked /unix and /lib/shlib. Then I checked /etc/wmgr. The error
shows up in /etc/wmgr. So probably, you did create the extra windows/devices,
but you would have to get around the wmgr. I suspect you might be able to use
them in some program, much as the "pty"s can be used by GNUEmacs, but you'll
probably be stuck until you find a way to modify wmgr.
