public class VkImportMemoryWin32HandleInfoKHR
extends org.lwjgl.system.Struct

```
import Win32 memory created on the same physical device.
Description

Importing memory objects 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 longer needed.

Applications can import the same underlying memory 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.

Valid Usage
- If handleType is not 0, it must be supported for import, as reported by VkExternalImageFormatProperties or VkExternalBufferProperties.
- The memory from which handle was exported, or the memory named by name must have been created on the same underlying physical device as device.
- If handleType is not 0, it must be defined as an NT handle or a global share handle.
- If handleType is not EXTERNAL_MEMORY_HANDLE_TYPE_OPAQUE_WIN32_BIT, EXTERNAL_MEMORY_HANDLE_TYPE_D3D11_TEXTURE_BIT, EXTERNAL_MEMORY_HANDLE_TYPE_D3D12_HEAP_BIT, or EXTERNAL_MEMORY_HANDLE_TYPE_D3D12_RESOURCE_BIT, name must be NULL.
- If handleType is not 0 and handle is NULL, name must name a valid memory resource of the type specified by handleType.
- If handleType is not 0 and name is NULL, handle must be a valid handle of the type specified by handleType.
- if handle is not NULL, name must be NULL.
- If handle is not NULL, it must obey any requirements listed for handleType in external memory handle types compatibility.
- If name is not NULL, it must obey any requirements listed for handleType in external memory handle types compatibility.
Valid Usage (Implicit)
- sType must be STRUCTURE_TYPE_IMPORT_MEMORY_WIN32_HANDLE_INFO_KHR
- If handleType is not 0, handleType must be a valid VkExternalMemoryHandleTypeFlagBits value
Member documentation
- sType – the type of this structure.
- pNext – NULL or a pointer to an extension-specific structure.
- handleType – specifies the type of handle or name.
- handle – the external handle to import, or NULL.
- name – a NULL-terminated UTF-16 string naming the underlying memory resource to import, or NULL.
