VkExportMetalDeviceInfoEXT

To export the Metal MTLDevice object underlying the VkPhysicalDevice associated with a VkDevice object, include a VkExportMetalDeviceInfoEXT structure in the pNext chain of the pMetalObjectsInfo parameter of a vkExportMetalObjectsEXT call.

The VkExportMetalDeviceInfoEXT structure is defined as:

typedef struct VkExportMetalDeviceInfoEXT {
    VkStructureType sType;
    const void* pNext;
    MTLDevice_id mtlDevice;
} VkExportMetalDeviceInfoEXT;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• mtlDevice is the Metal id<MTLDevice> object underlying the VkPhysicalDevice associated with the VkDevice object identified in the call. The implementation will return the MTLDevice in this member, or it will return NULL if no MTLDevice could be found underlying the VkPhysicalDevice object.
