I don't agree with that, since the other functions return the number of
characters printed as well.

ben@strontium:~/tmp$ cat t.c
int
main(void) {
        int n;
        char *p;

        n = printf("foo\n");
        printf("n=%d\n", n);

        n = asprintf(&p, "%d %d", 123, 456);
        printf("p=%s n=%d\n", p, n);

	/* etc */

        return (0);
}
ben@strontium:~/tmp$ ./a.out
foo
n=4
p=123 456 n=7
