```csharp
public void* ReadNext(int structSize)
```

### Parameters

**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): The size of the element to read.

### Returns

| Type                                                         | Description                                                       |

public void ReadNext<T>(out NativeArray<T> value, AllocatorManager.AllocatorHandle allocator) where T : unmanaged
```

### Parameters

**** (\[NativeArray\<T>]\(/engine/6000.7/script-reference/unity/collections/nativearray1)): Outputs a new array with length of 1. The read element is copied to the single index of this array.**** (\[AllocatorHandle]\(/engine/6000.7/script-reference/unity/collections/allocatormanager/allocatorhandle)): The allocator to use.
