* Module Name: ddisup.c
|
|

|
|
* This module contains code that handles calls to supplementary DDI entry points
|
|
* added as part of the Daytona release. These routines are currently only handled
|
|
* in the context of OpenGL, but will later be supported by 2D in general.

*
|
|
* 5-Jun-1994 Bill Clifford
|
|
* Initial version.
|
|
*
|
|
* 29-Jun-1994 Barry Tannenbaum
|
|
* Removed conditional compilation for OpenGL support. Now decided at
|
|
* runtime
|
|
*
|
|
* 1-Sep-1994 Barry Tannenbaum & Bill Clifford

* Use CriticalSection in DrvDescribePixelFormat
