To export a Windows handle representing the underlying resources of a Vulkan device memory object, call:
VkResult vkGetMemoryWin32HandleKHR( VkDevice device, const VkMemoryGetWin32HandleInfoKHR* pGetWin32HandleInfo, HANDLE* pHandle);
deviceis the logical device that created the device memory being exported.
pGetWin32HandleInfois a pointer to a VkMemoryGetWin32HandleInfoKHR structure containing parameters of the export operation.
pHandlewill return the Windows handle representing the underlying resources of the device memory object.
For handle types defined as NT handles, the handles returned by
vkGetMemoryWin32HandleKHR are owned by the application.
To avoid leaking resources, the application must release ownership of them
CloseHandle system call when they are no longer needed.
