Members
baseobj
- Structure used by the handle manager. Unused for a PDEVOBJ.
ppdevNext
- Pointer to the next PDEV in the list.
cPdevRefs
- Number of references to this PDEV.
cPdevOpenRefs
ppdevParent
- Pointer to the parent's PDEVOBJ. Points to this PDEV if no parent.
flags
- Flags. Can be a combination of the following values.
#define PDEV_DISPLAY 0x00001 #define PDEV_HARDWARE_POINTER 0x00002 #define PDEV_SOFTWARE_POINTER 0x00004 #define PDEV_GOTFONTS 0x00040 #define PDEV_PRINTER 0x00080 #define PDEV_ALLOCATEDBRUSHES 0x00100 #define PDEV_HTPAL_IS_DEVPAL 0x00200 #define PDEV_DISABLED 0x00400 #define PDEV_SYNCHRONIZE_ENABLED 0x00800 #define PDEV_FONTDRIVER 0x02000 #define PDEV_GAMMARAMP_TABLE 0x04000 #define PDEV_UMPD 0x08000 #define PDEV_SHARED_DEVLOCK 0x10000 #define PDEV_META_DEVICE 0x20000 #define PDEV_DRIVER_PUNTED_CALL 0x40000 #define PDEV_CLONE_DEVICE 0x80000
flAccelerated
hsemDevLock
- DEVOBJ lock, == HSEMAPHORE == PERESOURCE
hsemPointer
ptlPointer
- Current position of the mouse pointer, if any.
szlPointer
- Current dimensions of the pointer shape.
SpriteState
hlfntDefault
- Handle to the devices default logical font.
hlfntAnsiVariable
hlfntAnsiFixed
ahsurf
- Array of handles for the standard fill patterns. See phsurfPatterns in DrvEnablePDEV documentation.

pDevHTInfo
prfntActive
prfntInactive
cInactive
ajbo
- EBRUSHOBJ, was 0xFFFFFFFF on XP
cDirectDrawDisableLocks
TypeOneInfo
pvGammaRamp
- Gamma Ramp pointer.
RemoteTypeOne
- REMOTETYPEONENODE *
ulHorzRes
- slz if PDEV_META_DEVICE
ulVertRes
- get it from here.
pfnDrvSetPointerShape
- XP: win32k!WatchdogDrvSetPointerShape
pfnDrvMovePointer
- XP: win32k!WatchdogDrvMovePointer
pfnMovePointer
pfnDrvSynchronize
pfnDrvSynchronizeSurface (SURFACE *,RECTL *, FLONG)
pfnDrvSetPalette
pfnDrvNotify
- vNotify (ULONG, PVOID)
TagSig
- Tag Sign! 'Pdev'
pldev
- Pointer to the corresponding LDEVOBJ.
dhpdev
- Driver defined handle to the device.
ppalSurf
devinfo
gdiinfo
pSurface
- (CONTAINING_RECORD +10h = SURFOBJ), the pointer will start at SURFOBJ of the SURFACE structure.
hSpooler
pDesktopId
pGraphicsDevice
- PGRAPHICS_DEVICE see DISPLAY_DEVICE
ptlOrigion
pdmwDev
- Pointer to a single DEVMODEW structure, describing the current display settings. The size of the allocation is
DEVMODEW.dmSize + dmDriverExtra. Allocated with Tag GDITAG_DEVMODE ('Gdev').
DxDd_Flags
devAttr
- EngQueryDeviceAttribute, ENG_DEVICE_ATTRIBUTE
WatchDogContext
WatchDogs
apfn
- Driver Function pointer table. See winddi.h. Is filled in by GDI according to the DRVFN return from the driver.
eDirectDrawGlobal
Remarks
- The pool tag for the structure is 'GDev'
