Class KHRGetMemoryRequirements2

java.lang.Object

org.lwjgl.vulkan.KHRGetMemoryRequirements2

public class KHRGetMemoryRequirements2
extends Object

This extension provides new queries for memory requirements of images and buffers that can be easily extended by other extensions, without introducing any additional commands. The Vulkan 1.0 VkMemoryRequirements and VkSparseImageMemoryRequirements structures do not include sType and pNext members. This extension wraps them in new structures with these members, so an application can query a chain of memory requirements structures by constructing the chain and letting the implementation fill them in. A new command is added for each vkGet*MemoryRequrements command in core Vulkan 1.0.

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.
