Ok, if you insist:
******* BEGIN LAME FAQ ENTRY ********
Q1: I am trying to use GRX2.0, but there isn't any documentation.
Help!!
Q2: I can start a graphics session in GRX2.0, but when I follow the
code in the BitBlt test program, I keep getting strange errors!
A1: The best way to get an idea of the structure of GRX2.0 programs
is to copy TEST.H into your editor, undefine the #defines, and use
the given main() function. (Make sure you change it to type int!)
A2: Because the BitBlt demo uses TEST.H, the graphics mode is
initialized _before_ the demo even runs. Make _sure_ that the
graphics mode you desire has been intialized before you do a
GrCreateContext call. Otherwise, a NULL pointer is returned, with no
error!
***** END LAME FAQ ENTRY ********
I personally don't think I'm qualified for the actual manual, tho :)
Cheers,
Jeff
