PFND3D10DDI_DRAWINSTANCED callback function (d3d10umddi.h)
The DrawInstanced function draws particular instances of nonindexed primitives.
Syntax
PFND3D10DDI_DRAWINSTANCED Pfnd3d10ddiDrawinstanced;
void Pfnd3d10ddiDrawinstanced(
D3D10DDI_HDEVICE unnamedParam1,
UINT unnamedParam2,
UINT unnamedParam3,
UINT unnamedParam4,
UINT unnamedParam5
)
{...}
Parameters
unnamedParam1
hDevice [in]
A handle to the display device (graphics context).
unnamedParam2
VertexCountPerInstance [in]
The number of vertices per instance of the buffer that vertices are read from to draw the primitives.
unnamedParam3
InstanceCount [in]
The number of instances of the buffer that vertices are read from to draw the primitives.
unnamedParam4
StartVertexLocation [in]
The first vertex in the buffer that vertices are read from to draw the primitives.
unnamedParam5
StartInstanceLocation [in]
The first instance of the buffer that vertices are read from to draw the primitives.
Return value
None
Remarks
The driver can use the pfnSetErrorCb callback function to set an error code.
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 DrawInstanced (which typically should not happen), the driver can return D3DDDIERR_DEVICEREMOVED.
