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
-
physicalDevice
is the physical device from which to query the semaphore capabilities. -
pExternalSemaphoreInfo
is a pointer to a VkPhysicalDeviceExternalSemaphoreInfo structure describing the parameters that would be consumed by vkCreateSemaphore. -
pExternalSemaphoreProperties
is a pointer to a VkExternalSemaphoreProperties structure in which capabilities are returned.
