# VkImportMemoryWin32HandleInfoNV(3) Manual Page

## Name

VkImportMemoryWin32HandleInfoNV - Import Win32 memory created on the same physical device

Loading… please wait.

## C Specification

To import memory created on the same physical device but outside of the current Vulkan instance, add a VkImportMemoryWin32HandleInfoNV structure to the `pNext` chain of the VkMemoryAllocateInfo structure, specifying a handle to and the type of the memory.

The `VkImportMemoryWin32HandleInfoNV` structure is defined as:

    // Provided by VK_NV_external_memory_win32
    typedef struct VkImportMemoryWin32HandleInfoNV {
        VkStructureType                      sType;
        const void*                          pNext;
        VkExternalMemoryHandleTypeFlagsNV    handleType;
        HANDLE                               handle;
    } VkImportMemoryWin32HandleInfoNV;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `handleType` is `0` or a VkExternalMemoryHandleTypeFlagBitsNV value specifying the type of memory handle in `handle`.

- `handle` is a Windows `HANDLE` referring to the memory.

## Description

If `handleType` is `0`, this structure is ignored by consumers of the VkMemoryAllocateInfo structure it is chained from.

Valid Usage

- VUID-VkImportMemoryWin32HandleInfoNV-handleType-01327
  `handleType` must not have more than one bit set

- VUID-VkImportMemoryWin32HandleInfoNV-handle-01328
  `handle` must be a valid handle to memory, obtained as specified by `handleType`

Valid Usage (Implicit)

- VUID-VkImportMemoryWin32HandleInfoNV-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_IMPORT_MEMORY_WIN32_HANDLE_INFO_NV

- VUID-VkImportMemoryWin32HandleInfoNV-handleType-parameter
  `handleType` must be a valid combination of VkExternalMemoryHandleTypeFlagBitsNV values
