-/* Create a new capability class for objects allocating SIZE bytes for
- the user object with alignment ALIGNMENT (i.e. size does NOT
- include the struct hurd_cap_obj which is placed at the beginning of
- each capability object).
-
- The callback OBJ_INIT is used whenever a capability object in this
- class is created. The callback OBJ_REINIT is used whenever a
- capability object in this class is deallocated and returned to the
- slab. OBJ_REINIT should return a capability object that is not
- used anymore into the same state as OBJ_INIT does for a freshly
- allocated object. OBJ_DESTROY should deallocate all resources for
- this capablity object. Note that if OBJ_INIT or OBJ_REINIT fails,
- the object is considered to be fully destroyed. No extra call to
- OBJ_DESTROY will be made for such objects.
-
- The new capability class is returned in R_CLASS. If the creation
- fails, an error value will be returned. */
