NtGdiDdCreateSurfaceObject function

[This function is subject to change with each operating system revision. Instead, use the Microsoft DirectDraw and Microsoft Direct3DAPIs; these APIs insulate applications from such operating system changes, and hide many other difficulties involved in interacting directly with display drivers.]

Creates a kernel-mode surface object that represents the user-mode surface object referenced by puSurfaceLocal.

Syntax

HANDLE APIENTRY NtGdiDdCreateSurfaceObject(
  _In_ HANDLE             hDirectDrawLocal,
  _In_ HANDLE             hSurface,
  _In_ PDD_SURFACE_LOCAL  puSurfaceLocal,
  _In_ PDD_SURFACE_MORE   puSurfaceMore,
  _In_ PDD_SURFACE_GLOBAL puSurfaceGlobal,
  _In_ BOOL               bComplete
);

Parameters

hDirectDrawLocal [in]

Handle to the kernel-mode DirectDraw object.

hSurface [in]

Previous handle to the same surface. Used if the surface is being re-created after a mode switch.

puSurfaceLocal [in]

Pointer to the DD_SURFACE_LOCAL structure that represents the DirectDraw user-mode surface object with which to associate the allocated memory. See the DDK documentation for details.

puSurfaceMore [in]

Pointer to the DD_SURFACE_MORE structure that contains additional local data for each individual surface object. See the DDK documentation for details.

puSurfaceGlobal [in]

Pointer to the DD_SURFACE_GLOBAL structure that contains surface data shared globally with multiple surfaces. See the DDK documentation for details.

bComplete [in]

Kernel-mode object completion flag. Can be one of the following values.

(TRUE)

Complete all processing concerning the kernel-mode representation.

(FALSE)

Create the object, but do not set up internal data such as the memory pointer. Objects created using FALSE can be attached using NtGdiDdAttachSurface and are completed by a call to NtGdiDdCreateSurface.

Return value

If successful, this function returns a handle to the kernel-mode surface representation; otherwise it returns NULL.

Remarks

Applications are advised to use the DirectDraw and Direct3D APIs to create and manage graphics device objects. These constructs abstract the device creation process in a simplified and operating-system-independent way.
