QuickDraw 3D RAVE supports one type of device and one type of clipping on generic operating systems. The available device and clipping are defined by unions of type TQAPlatformDevice and TQAPlatformClip .
typedef union TQAPlatformDevice {
TQADeviceMemory memoryDevice;
} TQAPlatformDevice;
typedef union TQAPlatformClip {
void *region;
} TQAPlatformClip;
