|
* ==== == ======
|
||
|
|
* 06-jan-95 craige initial implementation
|
||
|
|
* 03-mar-95 craige added dprintf2
|
||
|
|
* 31-mar-95 craige add DPFInit to read WIN.INI for [DirectDraw] section;
|
||
|
|
* added dprintf3
|
||
|
|
* 01-apr-95 craige happy fun joy updated header file
|
||
|
|
* 06-apr-95 craige made stand-alone
|
||
|
|
* 18-jun-95 craige use negative dpf level to display ONLY that level
|
||
|
|
* 06-dec-95 jeffno Changed dprintf to use c-standard variable argument
|
||
|
|
* list techniques. Also added abs for NT
|
||
|
|
* 06-feb-96 colinmc added simple assertion mechanism for DirectDraw
|
||
|
|
* 15-apr-96 kipo added msinternal
|
||
|
|
* 20-may-96 andyco forced ansi entry points on all functions
