     173@item @code{@value{DIRPREFIX}name} is the data type used to
     174contain the name of a Classic API object.  It is an unsigned
     175thirty-two bit integer which can be treated as a numeric
     176value or initialized using @code{@value{DIRPREFIX}build_name} to
     177contain four ASCII characters.

     234type for the argument passed to each RTEMS task. In RTEMS 4.7
     235and older, this is an unsigned thirty-two bit integer.  In
     236RTEMS 4.8 and newer, this is based upon the C99 type @code{uintptr_t}
     237which is guaranteed to be an integer large enough to hold a
     238pointer on the target architecture.
