* **Assembly:** UnityEngine.BurstModule

## InterlockedOr(int, int)

Bitwise or as an atomic operation.

```csharp
public static int InterlockedOr(ref int location, int value)
```

### Parameters

**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): Where to atomically or the result into.**** (\[int]\(https\://learn.microsoft.com/dotnet/api/system.int32)): The value to be combined.

### Returns

| Type                                                       | Description                       |
| ---------------------------------------------------------- | --------------------------------- |
| [int](https://learn.microsoft.com/dotnet/api/system.int32) | The original value in `location`. |

### Remarks

Using the return value of this intrinsic may result in worse code-generation on some platforms (a compare-exchange loop), rather than a single atomic instruction being generated.
