Actually, if he is speaking about a GString object, the following snippet
does what he wants:

    if (string != 0 && string->len != 0)
        /* String is defined and has >0 length... */
    else
        /* String is not defined, or has 0 length... */

strlen() is defficient in a number of ways. First, it cannot store '\0'.
Second, it is usually O(n) instead of O(1).
