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;

Members

Note

A VkExternalMemoryImageCreateInfo structure with a non-zero handleTypes field 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 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 VkExternalMemoryHandleTypeFlagBits specifying one or more external memory handle types.

Valid Usage (Implicit)
  • VUID-VkExternalMemoryImageCreateInfo-sType-sType
    sType must be VK_STRUCTURE_TYPE_EXTERNAL_MEMORY_IMAGE_CREATE_INFO

  • VUID-VkExternalMemoryImageCreateInfo-handleTypes-parameter
    handleTypes must be a valid combination of VkExternalMemoryHandleTypeFlagBits values
