Class EXTExternalMemoryDmaBuf

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.
