VkExportMetalIOSurfaceInfoEXT(3)

Name

VkExportMetalIOSurfaceInfoEXT - Structure that identifies a VkImage object and corresponding Metal IOSurfaceRef object

C Specification

To export the Metal IOSurfaceRef object underlying a VkImage object, include a VkExportMetalIOSurfaceInfoEXT structure in the pNext chain of the pMetalObjectsInfo parameter of a vkExportMetalObjectsEXT call.

The VkExportMetalIOSurfaceInfoEXT structure is defined as:

// Provided by VK_EXT_metal_objects
typedef struct VkExportMetalIOSurfaceInfoEXT {
    VkStructureType    sType;
    const void*        pNext;
    VkImage            image;
    IOSurfaceRef       ioSurface;
} VkExportMetalIOSurfaceInfoEXT;

Members

  • sType is a VkStructureType value identifying this structure.

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

  • image is a VkImage.

  • ioSurface is the Metal IOSurfaceRef object underlying the VkImage object in image. The implementation will return the IOSurfaceRef in this member, or it will return NULL if no IOSurfaceRef could be found underlying the VkImage object.

Description

Valid Usage (Implicit)

  • VUID-VkExportMetalIOSurfaceInfoEXT-sType-sType
    sType must be VK_STRUCTURE_TYPE_EXPORT_METAL_IO_SURFACE_INFO_EXT

  • VUID-VkExportMetalIOSurfaceInfoEXT-image-parameter
    image must be a valid VkImage handle
