recursive sentence reverse [C]

how is my solution, /prog/-kun?

void
putwd(char *s)
{
        while (*s && !isspace(*s))
                putchar(*s++);
        putchar(' ');
}

char *
cdr(char *s)
{
        while (*s && !isspace(*s))
                ++s;
        while (isspace(*s))
                ++s;
        return *s ? s : NULL;
}

void
rprint(char *s)
{
        if (cdr(s))
                rprint(cdr(s));
        putwd(s);
}

int
main(void)
{
        rprint("anus my hax");
        putchar('\n');
        return 0;
}

Claim rejected. Working within the standard is a pointless endeavor that constrains programmers from achieving true works of greatness. If the compiler accepts it, it's good enough.

You are dismissed, as are your antiquated notions of standards and similar ilk.
