## Name

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

Loading... please wait.

## C Specification

To define a set of external memory handle types that may be used as backing store for an image, add a VkExternalMemoryImageCreateInfo structure to the `pNext` chain of the VkImageCreateInfo structure. The `VkExternalMemoryImageCreateInfo` structure is defined as:

    typedef struct VkExternalMemoryImageCreateInfo {
        VkStructureType                    sType;
        const void*                        pNext;
        VkExternalMemoryHandleTypeFlags    handleTypes;
    } VkExternalMemoryImageCreateInfo;

or the equivalent

    typedef VkExternalMemoryImageCreateInfo VkExternalMemoryImageCreateInfoKHR;

## Members

| Note A `VkExternalMemoryImageCreateInfo` structure must be included in the creation parameters for an image that will be bound to memory that is either exported or imported.

## Description

- `sType` is the type of this structure.

- `pNext` is `NULL` or a pointer to an extension-specific structure.

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

Valid Usage (Implicit)

- `sType` must be `VK_STRUCTURE_TYPE_EXTERNAL_MEMORY_IMAGE_CREATE_INFO`

- `handleTypes` must be a valid combination of VkExternalMemoryHandleTypeFlagBits values

- `handleTypes` must not be `0`
