C Specification
To import, or create, a Metal IOSurfaceRef
object to underlie a
VkImage object, include a VkImportMetalIOSurfaceInfoEXT
structure in the pNext
chain of the VkImageCreateInfo structure
in a vkCreateImage command.
The VkImportMetalIOSurfaceInfoEXT
structure is defined as:
// Provided by VK_EXT_metal_objects
typedef struct VkImportMetalIOSurfaceInfoEXT {
VkStructureType sType;
const void* pNext;
IOSurfaceRef ioSurface;
} VkImportMetalIOSurfaceInfoEXT;
Members
-
sType
is the type of this structure. -
pNext
isNULL
or a pointer to a structure extending this structure. -
ioSurface
isVK_NULL_HANDLE
or the MetalIOSurfaceRef
object that is to underlie the VkImage.
Description
If ioSurface
is not VK_NULL_HANDLE
, it will be used to underlie
the VkImage.
If ioSurface
is VK_NULL_HANDLE
, the implementation will create a
new IOSurface
to underlie the VkImage.
If provided, the app must ensure that the configuration of the
IOSurfaceRef
object is compatible with the configuration of the
VkImage.
Failure to do so results in undefined behavior.
