In http://www.lysator.liu.se/c/dmr-on-noalias.html, a copy of an article
posted here on comp.lang.c on 1988-03-20, Dennis Ritchie discussed both
const and noalias (the latter was dropped):
By way of introduction, the important thing about `const'
is that the current wording says, in section 3.3.4, that a
pointer to a const-qualified object may be cast to a pointer
to the plain object, but "If an attempt is made to modify the
pointed-to object by means of the converted pointer, the behavior
is undefined." Because function prototypes tend to convert your
pointers to const-qualified pointers, difficulties arise.
In discussion with various X3J11 members, I learned that this
section is now regarded as an inadvertant error, and no one
thinks that it will last in its current form. Nevertheless, it
seemed wisest to keep my comments in their original strong form.
The intentions of the committee are irrelevant; only their
document matters.
[...]
One of the simplest routines,
char *strchr(const noalias char *s, int c);
can return its first parameter. This first parameter must be
declared with `const noalias;' otherwise, it would be illegal
(by the constraints on assignment, 3.3.16.1) to pass the address
of a const or noalias object. That is, the type qualifiers
in the prototype are not merely an optional pleasantry of the
interface; they are required, if one is to pass some kinds of
data to this or most other library routines.
Unfortunately, there is no way in X3J11's language for strchr
to return the value it promises to, because of the semantics
of return (3.6.6.4) and casts (3.3.4). Whether the stripping
of the const and noalias qualifiers is done by cast inside
strchr, or implicitly by its return statement, strchr returns
a pointer that (because of `const') cannot be stored through,
and (because of `noalias') cannot even be dereferenced; by the
rules, it is useless. (Incidentally, I think this observation
was made by Tom Plum several years ago; it's disconcerting that
the inconsistency remains.)
This was a complaint about an interaction between "const" and "noalias".
But there's *still* a serious problem with the strchr() and strrchr()
functions. It's not an inherent probelm with "const", just with the way
it's used in the standard library.
#include <stdio.h>
#include <string.h>
int main(void) {
const char s[] = "hello";
char *ptr = strchr(s, 'h');
*ptr = 'H';
puts(s);
}
Since strchr takes a `const char*` argument and returns a (non-const)
`char*` result, it can return a non-const pointer to a const char
object. The above program prints "Hello" on my system, violating the
"const" on the declaration of s. No diagostic is required (and, FWIW,
gcc doesn't warn).
C++ fixes this by providing two overloaded version of strchr():
const char* strchr(const char* s, int c);
char* strchr( char* s, int c);
ANSI C probably should have done something similar, but giving them
distinct names, perhaps strchr() and strcchr() (and likewise strrchr()
and strrcchr()).
