# Serialize

> Writes the contents of the library to the provided memory, to be provided back to the runtime at a later time.

Writes the contents of the library to the provided memory, to be provided back to the runtime at a later time.

## Syntax

```cpp theme={null}
HRESULT Serialize(
    void  pData,
    SIZE_T DataSizeInBytes
)
```

### Parameters

*pData \[out]*\
Type: void \*

Specifies a pointer to the data. This memory must be readable and writable up to the input size. This data can be saved and provided to [CreatePipelineLibrary](/reference/graphics/d3d12/interfaces/id3d12device1/methods/id3d12device1_createpipelinelibrary_public) at a later time, including future instances of this or other processes. The data becomes invalidated if the runtime or driver is updated, and is not portable to other hardware or devices.

*DataSizeInBytes*\
Type: SIZE\_T

The size provided must be at least the size returned from [GetSerializedSize](/reference/graphics/d3d12/interfaces/id3d12pipelinelibrary/methods/id3d12pipelinelibrary_getserializedsize_public).

### Return value

Type: HRESULT

This method returns an HRESULT success or error code, including E\_INVALIDARG if the buffer provided isn't big enough.

## Remarks

Refer to the remarks and examples for [CreatePipelineLibrary](/reference/graphics/d3d12/interfaces/id3d12device1/methods/id3d12device1_createpipelinelibrary_public).

## 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
