# VkExternalMemoryImageCreateInfoNV(3) Manual Page

## Name

VkExternalMemoryImageCreateInfoNV - Specify that an image may be backed by external memory

Loading… please wait.

## C Specification

If the `pNext` chain includes a `VkExternalMemoryImageCreateInfoNV` structure, then that structure defines a set of external memory handle types that may be used as backing store for the image.

The `VkExternalMemoryImageCreateInfoNV` structure is defined as:

    // Provided by VK_NV_external_memory
    typedef struct VkExternalMemoryImageCreateInfoNV {
        VkStructureType                      sType;
        const void*                          pNext;
        VkExternalMemoryHandleTypeFlagsNV    handleTypes;
    } VkExternalMemoryImageCreateInfoNV;

## Members

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

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

- `handleTypes` is zero or a bitmask of VkExternalMemoryHandleTypeFlagBitsNV specifying one or more external memory handle types.

## Description

Valid Usage (Implicit)

- VUID-VkExternalMemoryImageCreateInfoNV-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_EXTERNAL_MEMORY_IMAGE_CREATE_INFO_NV`

- VUID-VkExternalMemoryImageCreateInfoNV-handleTypes-parameter
  `handleTypes` must be a valid combination of VkExternalMemoryHandleTypeFlagBitsNV values
