KHRExternalSemaphore (LWJGL 3.2.3 - Vulkan)

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

```
public final class KHRExternalSemaphore
extends java.lang.Object
```
An application using external memory may wish to synchronize access to that memory using semaphores. This extension enables an application to create semaphores from which non-Vulkan handles that reference the underlying synchronization primitive can be exported.
Promotion to Vulkan 1.1

All functionality in this extension is included in core Vulkan 1.1, with the KHR suffix omitted. The original type, enum and command names are still available as aliases of the core functionality.
