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
