PFND3DDDI_SETSTREAMSOURCE callback function (d3dumddi.h)

The SetStreamSource function binds a portion of a vertex stream source to a vertex buffer.

Syntax

PFND3DDDI_SETSTREAMSOURCE Pfnd3dddiSetstreamsource;

HRESULT Pfnd3dddiSetstreamsource(
  HANDLE hDevice,
  const D3DDDIARG_SETSTREAMSOURCE *unnamedParam2
)
{...}

Parameters

hDevice

A handle to the display device (graphics context).

unnamedParam2

pData [in]

A pointer to a D3DDDIARG_SETSTREAMSOURCE structure that specifies the portion of the vertex stream source to bind.

Return value

SetStreamSource returns S_OK or an appropriate error result if the portion of the vertex stream source is not successfully bound.

Remarks

The Microsoft Direct3D runtime calls the user-mode display driver's SetStreamSource function to store vertex data of multiple vertex formats in a single vertex data stream. The runtime notifies the driver of where vertex data of a particular format is located in the vertex data stream by supplying the stream offset, in bytes, to the beginning of that vertex data.
