Parameters

StreamNumber

[in] Specifies the data stream, in the range from 0 to the maximum number of streams -1.

pStreamData

[in] Pointer to an IDirect3DVertexBuffer9 interface, representing the vertex buffer to bind to the specified data stream.

OffsetInBytes

[in] Offset from the beginning of the stream to the beginning of the vertex data, in bytes. To find out if the device supports stream offsets, see theD3DDEVCAPS2_STREAMOFFSET constant in D3DDEVCAPS2.

Stride

[in] Stride of the component, in bytes. See Remarks.

Remarks

When a flexible vertex format (FVF) vertex shader is used, the stride of the vertex stream must match the vertex size, computed from the FVF. When a declaration is used, the stride should be greater than or equal to the stream size computed from the declaration.

When an application no longer holds a references to this interface, the interface will automatically be freed.
