[9front] Display graphics by writing to /dev/<device>

[9front] Display graphics by writing to /dev/<device>

[Alexander Shendi]

Dear list,

I'm determined to program under 9front. I would like to ask, if I could display (bitmap) graphics in a window by writing stuff to some /dev/<devicename>. I think this is definitely possible, but am unsure which device to use snd where the process is documented.

I'm sorry if this is a Frequently Asked Stupid Question (FASQ).

Thanks in advance,

Alexander Shendi

that is exactly how devdraw works. you write messages to a file in
/dev, and stuff happens on the screen (http://man.9front.org/3/draw).
see http://man.9front.org/2/draw for a higher level interface.

man 2 draw ==> C API
man 3 draw ==> device api

Thank you very much. That was the info I needed. I've read draw(3), image(6) and color(6) :) The interface seems to be rather nice and tractable.

Actually there are also more or less experimental Widget libraries that build upon devdraw/libdraw: http://shithub.us/tevo/widget/HEAD/info.html (didn't try that yet but there is an example program in the repository) and https://github.com/knusbaum/duit (written in Go)
