urgh, a software question :-) I need to write some X Windows code (X11R5, so
it makes the ten year rule!). Nothing fancy - no GUI needed, just pixel ops on
the root window.
Does anyone have any pointers to good online tutorials / other resources?
I think the last time I coded anything specifically for X was around the time
R5 was released, so memory is rather hazy, and I don't think I've got any
paper-based info here at home.
cheers!

Well, there hasn't changed a lot - at least for the basic stuff. A pixel
is still a rather crude dot on some bitplane. So if you still got some
old paper, use it. Beside that, http://www.the-labs.com/ is a primer
source for online-information about X11 - at least if you got some prior
programming knowledge :)
Check:
http://www.the-labs.com/X11/XLib-Manual/
Beside that, if you want to draw (vector based) stuff, the antigrain lib
( http://www.antigrain.com/ ) is worth a look. Extreme fast rendering and
complete OS independent.

It might not help, but I've been using SDL lately. It eliminates the
need to get caught up in X and allows you to be cross platform (win32,
mac & linux).
I use it for various emulators when they want to display using simple
bitmap hardware.

Hmm, interesting.
I'm trying to pack OS + enough of X to display pixel data into 32MB, but for
the application in mind I'll need to source data externally anyway - so it
might be possible to NFS-mount a remote drive with extra goodies on.
(I'm looking at other possibilities too, such as using SVGALib rather than X -
but I like X for its portability and remote display abilities)

IIRC there is somthing similar for GDK/GTK.
If you are using some flavor of Linux yo may get away by simply
scribbling into the kernel framebuffer device too.

Well I'm trying to avoid being too heavyweight; all I need are a few pixel ops

at SVGALib (vgagl) and that seems to do exactly what I need - plus it means I
don't need any of X at all (thus freeing up some storage space).

I tried doing exactly that yesterday and locked the machine up ;-)
I'd be using DOS rather than Linux if it wasn't for the networking side; I
don't really fancy writing a socketed app under DOS, but it's pretty easy
under Linux at least.

Well, I can act as a resource at need. I've done plenty of X
programming. Drop me a line off-list explaining what you're after and
I'll be happy to have a crack at it.
You might be able to write to me directly; for all that your address is
@yahoo.co.uk, I looked at the headers of your list mail, and it might
work - I can't recall whether we've corresponded directly in the past.
But I'd suggest a copy to mouse at netbsd.org as well if we haven't.
