octstr_compare

Hi All!

What are think about the add following code into octstr.c/octstr_compare?

int octstr_compare(const Octstr *ostr1, const Octstr *ostr2)
{
    int ret;
    long len;

    seems_valid(ostr1);
    seems_valid(ostr2);

+    if ((ostr1 == NULL) && (ostr2 == NULL))
+       return 0;
        
    if (ostr1->len < ostr2->len)
        len = ostr1->len;
    else
        len = ostr2->len;

    if (len == 0) {
        if (ostr1->len == 0 && ostr2->len > 0)
            return -1;
        if (ostr1->len > 0 && ostr2->len == 0)
            return 1;
        return 0;
    }

    ret = memcmp(ostr1->data, ostr2->data, len);
    if (ret == 0) {
        if (ostr1->len < ostr2->len)
            ret = -1;
        else if (ostr1->len > ostr2->len)
            ret = 1;
    }
    return ret;
}
