Title: Action item 2000-05-007 ( restrict )

Revision Date: 2000-05-25

Source: Ulrich Drepper

Action: for review


~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The rules for using restrict are (hopefully) following those the ISO C
committee used to determine which functions of the ISO C library
should get the restrict keyword added to the parameter list.  They are
as follows (let me know if you think the rules are incomplete or
wrong):

- only functions with two or more parameters need restrict

- additionally at least two of the objects pointed to must have the
  same type.  I.e.,

	int foo (int *, double *)

  does not need a restrict

- an exception to the above rule comes with pointers to structures.  Since
  the standard does not define the structures in all details we must assume
  the worst case which is that it contains an element of the type described
  by one of the other parameters.  I.e.,

	int bar (int restrict *, struct baz restrict *)

  needs restrict since the structure baz can potentially contain an element
  of type `int'.


With these rules the following editing rules on top of the draft 3 are
necessary.  I hope it's complete but am also sure I made the one or
the other mistake.
