KHRZeroInitializeWorkgroupMemory (LWJGL 3.3.1 - Vulkan)

java.lang.Object
- org.lwjgl.vulkan.KHRZeroInitializeWorkgroupMemory

```
public final class KHRZeroInitializeWorkgroupMemory
extends java.lang.Object
```
This extension allows the use of a null constant initializer on shader Workgroup memory variables, allowing implementations to expose any special hardware or instructions they may have. Zero initialization is commonly used by applications running untrusted content (e.g. web browsers) as way of defeating memory-scraping attacks.
Promotion to Vulkan 1.3

Functionality in this extension is included in core Vulkan 1.3, with the KHR suffix omitted. The original type, enum and command names are still available as aliases of the core functionality.
