org.lwjgl.vulkan.KHRExternalMemoryCapabilities

public class KHRExternalMemoryCapabilities
extends java.lang.Object

An application may wish to reference device memory in multiple Vulkan logical devices or instances, in multiple processes, and/or in multiple APIs. This extension provides a set of capability queries and handle definitions that allow an application to determine what types of "external" memory handles an implementation supports for a given set of use cases.

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.

See GetPhysicalDeviceExternalBufferProperties.

Parameters:

physicalDevice - the physical device from which to query the buffer capabilities.

pExternalBufferInfo - points to an instance of the VkPhysicalDeviceExternalBufferInfo structure, describing the parameters that would be consumed by CreateBuffer.

pExternalBufferProperties - points to an instance of the VkExternalBufferProperties structure in which capabilities are returned.
