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:

// Provided by VK_VERSION_1_1
typedef struct VkExternalMemoryImageCreateInfo {
    VkStructureType                    sType;
    const void*                        pNext;
    VkExternalMemoryHandleTypeFlags    handleTypes;
} VkExternalMemoryImageCreateInfo;

or the equivalent

// Provided by VK_KHR_external_memory
typedef VkExternalMemoryImageCreateInfo VkExternalMemoryImageCreateInfoKHR;



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.


  • sType is the type of this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

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

Valid Usage (Implicit)

  • handleTypes must be a valid combination of VkExternalMemoryHandleTypeFlagBits values

  • handleTypes must not be 0
