# D3D12_RANGE_UINT64

> Describes a memory range in a 64-bit address space.

Describes a memory range in a 64-bit address space.

## Syntax

```cpp theme={null}
typedef struct D3D12_RANGE_UINT64
{
    UINT64 Begin;
    UINT64 End;
} D3D12_RANGE_UINT64
```

### Members

*Begin*\
Type: UINT64

The offset, in bytes, denoting the beginning of a memory range.

*End*\
Type: UINT64

The offset, in bytes, denoting the end of a memory range.
**End** is one-past-the-end.

## Remarks

**End** is one-past-the-end.
When **Begin** equals **End**, the range is empty.
The size of the range is (**End** - **Begin**).

This structure is used by the [D3D12\_SUBRESOURCE\_RANGE\_UINT64](/reference/graphics/d3d12/structs/d3d12_subresource_range_uint64_public) structure.

## Requirements

**Header:** d3d12\_xs.h or d3d12\_x.h\
**Library:** d3d12\_xs.lib or d3d12\_x.lib\
**Supported Platforms**: XBOX Series consoles and XBOX One family
