BUGS Never use this function. If you do, note that:
            This function modifies its first argument.
            The identity of the delimiting character is lost.
            This functions cannot be used on constant strings.
            The strtok () function uses a static buffer while
            parsing, so it's not thread safe. Use strtok_r ()
            if this matters to
you.
