The following is a list of GDI and DDI functions that are obsolete in Windows NT 4.0:
| DrvGetResourceId | EngCreateSurface |
| DrvPlgBlt | EngPlayJournal |
| DrvQueryObjectData | EngPlgBlt |
| DrvRestartPDEV | EngStartBandPage |
| EngCreateJournal |
You need to remove calls to the obsolete EngXxx functions from your driver, or your driver will not compile and/or link.
The function indexes for the obsolete DrvXxx functions have been removed from GDI, and GDI no longer makes calls to these functions. Leaving these functions in your driver does no harm, but they won’t be used by GDI.
