Draw routine
The Draw function draws nonindexed primitives.
Syntax
PFND3D10DDI_DRAW Draw;
VOID APIENTRY Draw(
_In_ D3D10DDI_HDEVICE hDevice,
_In_ UINT VertexCount,
_In_ UINT StartVertexLocation
)
{ ... }
Parameters
- hDevice [in]
-
A handle to the display device (graphics context).
- VertexCount [in]
-
The number of vertices in the vertex buffer that vertices are read from to draw the primitives.
- StartVertexLocation [in]
-
The first vertex in the vertex buffer that vertices are read from to draw the primitives.
Return value
None
The driver can use the pfnSetErrorCb callback function to set an error code. For more information about setting error codes, see the following Remarks section.
Remarks
The driver should not encounter any error, except for D3DDDIERR_DEVICEREMOVED. Therefore, if the driver passes any error, except for D3DDDIERR_DEVICEREMOVED, in a call to the pfnSetErrorCb function, the Direct3D runtime will determine that the error is critical. Even if the device was removed, the driver is not required to return D3DDDIERR_DEVICEREMOVED; however, if device removal interfered with the operation of Draw (which typically should not happen), the driver can return D3DDDIERR_DEVICEREMOVED.
