EXTExternalMemoryDmaBuf (LWJGL 3.2.3 - Vulkan)

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

```
public final class EXTExternalMemoryDmaBuf
extends java.lang.Object
```
A dma_buf is a type of file descriptor, defined by the Linux kernel, that allows sharing memory across kernel device drivers and across processes. This extension enables applications to import a dma_buf as VkDeviceMemory; to export VkDeviceMemory as a dma_buf; and to create VkBuffer objects that can be bound to that memory.
