org.lwjgl.vulkan.KHRGetMemoryRequirements2

public class KHRGetMemoryRequirements2
extends java.lang.Object

This extension provides new entry points to query memory requirements of images and buffers in a way that can be easily extended by other extensions, without introducing any further entry points. The Vulkan 1.0 VkMemoryRequirements and VkSparseImageMemoryRequirements structures do not include a sType/pNext, this extension wraps them in new structures with sType/pNext 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 ftext: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.
