org.lwjgl.vulkan.KHRExternalSemaphoreCapabilities

public class KHRExternalSemaphoreCapabilities
extends java.lang.Object

An application may wish to reference device semaphores 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" semaphore 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.

Method Detail

nvkGetPhysicalDeviceExternalSemaphorePropertiesKHR

public static void nvkGetPhysicalDeviceExternalSemaphorePropertiesKHR(VkPhysicalDevice physicalDevice,
                                                                      long pExternalSemaphoreInfo,
                                                                      long pExternalSemaphoreProperties)

Unsafe version of: GetPhysicalDeviceExternalSemaphorePropertiesKHR

vkGetPhysicalDeviceExternalSemaphorePropertiesKHR

public static void vkGetPhysicalDeviceExternalSemaphorePropertiesKHR(VkPhysicalDevice physicalDevice,
                                                                     VkPhysicalDeviceExternalSemaphoreInfo pExternalSemaphoreInfo,

See GetPhysicalDeviceExternalSemaphoreProperties.

Parameters:

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

pExternalSemaphoreInfo - points to an instance of the VkPhysicalDeviceExternalSemaphoreInfo structure, describing the parameters that would be consumed by CreateSemaphore.

pExternalSemaphoreProperties - points to an instance of the VkExternalSemaphoreProperties structure in which capabilities are returned.
