From The Free On-line Dictionary of Computing (27 SEP 03) [foldoc]:

  built-in
       
          (Or "primitive") A built-in function or operator is one
          provided by the lowest level of a language implementation.
          This usually means it is not possible (or efficient) to
          express it in the language itself.  Typical examples are the
          basic arithmetic and {Boolean} operators (in {C} syntax: +, -,
          *, /, %, !, &&, ||), bit manipulation operators (~, &, |, ^)
          and I/O primitives.  Other common functions may be provided in
          libraries but are not built-in if they are written in the
          language being implemented.
