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
isNULL
or a pointer to a structure extending this structure. -
image
is a VkImage. -
ioSurface
is the Metal IOSurfaceRef object underlying the VkImage object inimage
. The implementation will return the IOSurfaceRef in this member, or it will returnNULL
if no IOSurfaceRef could be found underlying the VkImage object.
