C Specification

The type id<MTLCommandQueue> is defined in Apple’s Metal framework, but to remove an unnecessary compile time dependency, an incomplete type definition of MTLCommandQueue_id is provided in the Vulkan headers:

// Provided by VK_EXT_metal_objects
#ifdef __OBJC__
@protocol MTLCommandQueue;
typedef __unsafe_unretained id<MTLCommandQueue> MTLCommandQueue_id;
#else
typedef void* MTLCommandQueue_id;
#endif
