Binds a vertex buffer to a device data stream. For more information, see Setting the Stream Source.
UINT StreamNumber, IDirect3DVertexBuffer9 *pStreamData, UINT OffsetInBytes, UINT Stride );
- [in] Specifies the data stream, in the range from 0 to the maximum number of streams -1.
- [in] Pointer to an IDirect3DVertexBuffer9 interface, representing the vertex buffer to bind to the specified data stream.
- [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 the D3DDEVCAPS2_STREAMOFFSET constant in D3DDEVCAPS2.
- [in] Stride of the component, in bytes. See Remarks.
If the method succeeds, the return value is D3D_OK.
If the method fails, the return value can be D3DERR_INVALIDCALL.
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.
