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.
