# QNX71NetworkStack

> The network stack to build a QNX 7.1 player against.

## Definition

* **Type:** Enum
* **Namespace:** [UnityEditor](/engine/6000.7/script-reference/unityeditor.md)
* **Assembly:** UnityEditor.CoreModule

```csharp
public enum QNX71NetworkStack
```

## Remarks

QNX 7.1 provides two network stacks, and Unity builds a separate player variation for each one. QNX 8.0 provides only io-sock, so it ignores this setting.

Selecting io-sock requires a QNX 7.1 SDK that provides the io-sock headers. A build against an SDK without them fails and names the SDK path in the error.
