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
-
sTypeis a VkStructureType value identifying this structure. -
pNextisNULLor a pointer to a structure extending this structure. -
ioSurfaceis VK_NULL_HANDLE or the Metal IOSurfaceRef 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.
