You must use this SDK with QNX Neutrino 6.2.0 or later.

For general information about working with the DDK source code, see About Driver Development Kits.

Assumptions

We assume you have a basic familiarity with graphics cards, concepts, and terminology (e.g. pixels, spans, blitting, alpha-blending, chroma-keying, and raster operations).

You'll also need sufficient hardware documentation for your graphics chip in order to be able to program all the registers. A working knowledge of the C language is essential.
