## 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 An instance of VkExternalMemoryImageCreateInfo 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
