| === Description |
| |
| An application using external memory may wish to synchronize access to that |
| memory using fences. |
| This extension enables an application to create fences 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. |
