public class VkImportMemoryWin32HandleInfoKHR extends org.lwjgl.system.Struct<VkImportMemoryWin32HandleInfoKHR> implements org.lwjgl.system.NativeResource
Import Win32 memory created on the same physical device.
Description

Importing memory object payloads 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 handle ownership using the CloseHandle system call when the handle is no longer needed. For handle types defined as NT handles, the imported memory object holds a reference to its payload.

Note

Non-NT handle import operations do not add a reference to their associated payload. If the original object owning the payload is destroyed, all resources and handles sharing that payload will become invalid.

Applications can import the same payload into multiple instances of Vulkan, into the same instance from which it was exported, and multiple times into a given Vulkan instance. In all cases, each import operation must create a distinct VkDeviceMemory object.
