    UINT NumViews,
    const D3D12_VERTEX_BUFFER_VIEW  pViews
)
```

### Parameters

*StartSlot \[in]*\
Type: UINT

Index into the device's zero-based array to begin setting vertex buffers.

*NumViews \[in]*\
Type: UINT

The number of views in the <i>pViews</i> array.

*pViews \[in, optional]*\
Type: const D3D12\_VERTEX\_BUFFER\_VIEW \*

Specifies the vertex buffer views in an array of [D3D12\_VERTEX\_BUFFER\_VIEW](/reference/graphics/d3d12/structs/d3d12_vertex_buffer_view_public) structures.

### Return value

Type: void

None.

## Requirements

**Header:** d3d12\_xs.h or d3d12\_x.h\
**Library:** d3d12\_xs.lib or d3d12\_x.lib\
