To import a semaphore payload from a Zircon event handle, call:
// Provided by VK_FUCHSIA_external_semaphore VkResult vkImportSemaphoreZirconHandleFUCHSIA( VkDevice device, const VkImportSemaphoreZirconHandleInfoFUCHSIA* pImportSemaphoreZirconHandleInfo);
deviceis the logical device that created the semaphore.
pImportSemaphoreZirconHandleInfois a pointer to a VkImportSemaphoreZirconHandleInfoFUCHSIA structure specifying the semaphore and import parameters.
Importing a semaphore payload from a Zircon event handle transfers ownership of the handle from the application to the Vulkan implementation. The application must not perform any operations on the handle after a successful import.
Applications can import the same semaphore payload into multiple instances of Vulkan, into the same instance from which it was exported, and multiple times into a given Vulkan instance.
