But if you return and duplicate, you have no chance to free() the original string, no?

Ah, I see your confusion. Do this:

    RETVAL_STRINGL(str, strlen, 1);
    free(str);

The trick is that the RETVAL_* macros simply fill in the magic return_value zval whereas the RETURN_* macros return straight away. -Rasmus
