C Specification

To export Metal objects from Vulkan objects, the app must first indicate the intention to do so during the creation of the Vulkan object, by including one or more VkExportMetalObjectCreateInfoEXT structures in the pNext chain of the VkInstanceCreateInfo, VkMemoryAllocateInfo, VkImageCreateInfo, VkImageViewCreateInfo, VkBufferViewCreateInfo, VkSemaphoreCreateInfo, or VkEventCreateInfo, in the corresponding Vulkan object creation command.

The VkExportMetalObjectCreateInfoEXT structure is defined as:

// Provided by VK_EXT_metal_objects
typedef struct VkExportMetalObjectCreateInfoEXT {
    VkStructureType                       sType;
    const void*                           pNext;
    VkExportMetalObjectTypeFlagBitsEXT    exportObjectType;
} VkExportMetalObjectCreateInfoEXT;

Members

  • sType is a VkStructureType value identifying this structure.

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

  • exportObjectType is a VkExportMetalObjectTypeFlagBitsEXT indicating the type of Metal object that the application may request to be exported from the Vulkan object.

Description

Valid Usage (Implicit)

  • VUID-VkExportMetalObjectCreateInfoEXT-sType-sType
    sType must be VK_STRUCTURE_TYPE_EXPORT_METAL_OBJECT_CREATE_INFO_EXT

  • VUID-VkExportMetalObjectCreateInfoEXT-exportObjectType-parameter
    If exportObjectType is not 0, exportObjectType must be a valid VkExportMetalObjectTypeFlagBitsEXT value
