About This Book

The Graphics Adapter Device Driver (GRADD) Reference supports OS/2 Warp on 
the Intel hardware platform.  The information in this book describes the 
GRADD driver model, how the related components work together, and why the 
GRADD model enhances OS/2 Warp device-driver support. 

Detailed descriptions of control structures, data structures, and I/O 
formats have been included to help you understand and use the interfaces. 

Developers using this book should be familiar with the C or assembler 
programming language and the OS/2 operating system.
