C Specification

Semaphores may support import and export of their payload to external handles. To query the external handle types supported by semaphores, call:

void vkGetPhysicalDeviceExternalSemaphoreProperties(
    VkPhysicalDevice                            physicalDevice,
    const VkPhysicalDeviceExternalSemaphoreInfo* pExternalSemaphoreInfo,
    VkExternalSemaphoreProperties*              pExternalSemaphoreProperties);

or the equivalent command

void vkGetPhysicalDeviceExternalSemaphorePropertiesKHR(
    VkPhysicalDevice                            physicalDevice,
    const VkPhysicalDeviceExternalSemaphoreInfo* pExternalSemaphoreInfo,
    VkExternalSemaphoreProperties*              pExternalSemaphoreProperties);

Parameters

Description

Valid Usage (Implicit)
  • physicalDevice must be a valid VkPhysicalDevice handle

  • pExternalSemaphoreInfo must be a valid pointer to a valid VkPhysicalDeviceExternalSemaphoreInfo structure

  • pExternalSemaphoreProperties must be a valid pointer to a VkExternalSemaphoreProperties structure
