OK, I posted a similar question a week or two ago and got absolutely no
response. So here it comes again because I know SOMEONE has to have an
answer...

I am writing a full screen application using Vio calls and I need to muck
about with the VGA's DAC registers. In looking through the header files I
found the structure VIOCOLORREG and thought that it would let me change
the values of the DAC. So I looked for the function call that would take
this structure and do something important with it. The functions are
VioGetState and VioSetState. The problem seems to be that these functions
can also take 5 other structures, with seemingly no differences aside from
their size (in some cases) and the value of type. Now I suppose that type
is the key value here, but I have no idea of what is needed and/or if this
is the correct idea or not anyway.

I really need an answer here.

Thanks
Keith
