NtGdiDdCanCreateD3DBuffer function

  • Article

[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.]

Determines whether the driver can create a driver-level command or vertex buffer of the specified description.

Syntax

DWORD APIENTRY NtGdiDdCanCreateD3DBuffer(
  _In_    HANDLE                   hDirectDraw,
  _Inout_ PDD_CANCREATESURFACEDATA puCanCreateSurfaceData
);

Parameters

hDirectDraw [in]

Handle to the DD_DIRECTDRAW_GLOBAL structure representing the DirectDraw object.

puCanCreateSurfaceData [in, out]

Pointer to a DD_CANCREATESURFACEDATA structure. This structure contains the information required for the driver to determine whether a command or vertex buffer can be created.

Return value

NtGdiDdCanCreateD3DBuffer returns one of the following callback codes.

Return code Description
DDHAL_DRIVER_HANDLED
 The driver has performed the operation and returned a valid return code for that operation. If this code is DD_OK, DirectDraw or Direct3D proceeds with the function. Otherwise, DirectDraw or Direct3D returns the error code provided by the driver and aborts the function.
DDHAL_DRIVER_NOTHANDLED
 The driver has no comment on the requested operation. If the driver is required to have implemented a particular callback, DirectDraw or Direct3D reports an error condition. Otherwise, DirectDraw or Direct3D handles the operation as if the driver callback had not been defined by executing the DirectDraw or Direct3D device-independent implementation.
