To import a semaphore payload from a Windows handle, call:
// Provided by VK_KHR_external_semaphore_win32 VkResult vkImportSemaphoreWin32HandleKHR( VkDevice device, const VkImportSemaphoreWin32HandleInfoKHR* pImportSemaphoreWin32HandleInfo);
deviceis the logical device that created the semaphore.
pImportSemaphoreWin32HandleInfois a pointer to a VkImportSemaphoreWin32HandleInfoKHR structure specifying the semaphore and import parameters.
Importing a semaphore payload from Windows handles does not transfer
ownership of the handle to the Vulkan implementation.
For handle types defined as NT handles, the application must release
ownership using the
CloseHandle system call when the handle is no
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.
