 74 * @brief
 75 * Type for mach_port_kobject_description() only.
 76 *
 77 * @discussion
 78 * This type preserved the `IOT_*` values that @c ipc_kobject_type_t used
 79 * to carry, whose ABI of this type was known to debugging tools of userspace,
 80 * by copying XNU's source.
 81 *
 82 * This provides a guaranteed stable interface now (however no guarantee
 83 * is made that values are still in use).
 84 *
 85 * Values should never be removed to that list, merely abandonned with
 86 * a comment.
