[Coco] OS-9 graphics using C

[Stephen H. Fischer]

Hi,

If you are serious about graphics I have several books for about the level
of OS-9 "C".

I even typed in the source for one and had planned the methods to use them
under OS-9 "C".

I am not sure if this is the right book but it is the first one I got my
hands on. I have several.

Just stick this into Search.com
High Performance CAD Graphics in C by Lee Adams
"isbn+0-8306-9359-9"

NOTE: I generated a parallel set of CGfx library routines that are much
better and much faster using buffered calls.

All free for the asking and a willingness to pass onto the next person if
not useful to you.

Hey guys,

So I have been continuing to experiment and learn to write simple programs
for OS-9 in C.  I have reached the point where I'd like to manipulate the
screen, such as background/foreground colors and locating the cursor in
specific parts, etc.  The documentation I have checked so far is "Microware
C Compiler User’s Guide" which explains about standard input/output,
compiling, etc.  I also have been through "The complete Rainbow guide to
os-9 level II. volume 1: a beginners guide to windows".  This has taught me
how to use the "display, wcreate, iniz" commands etc in OS9 to manipulate
the screen.  But I still lack the knowledge of how to perform those commands
from C. And finally "The NitrOS-9" level 2 windowing system" which again
taught me alot about manipulating windows in os9 but not how to do any of
that stuff from C.  I suspect I will somehow need to use the _os9 system
call in C, but I have no reference as to the possible commands I can do with
that.  Any help is appreciated as always! :-)
