Ok, but then what do we need scopedData for? If we're returning a char* and
it's not zero-terminated I don't see how it can be used.

So far I've got this:

/** Extract a zero-terminated string.
    The caller takes ownership. */
const char *OutBuffer::extractString()
{
    if (!data || data[offset] != '\0')
        writeByte(0);
    char *p;
    p = (char *)data;
    data = NULL;
    offset = 0;
    size = 0;
    return p;
}

/** Verify the internal buffer is zero-terminated
    and return a reference to it. */
const char *OutBuffer::scopedString()
{
    assert(data && data[offset] == '\0');
    return (char *)data;
}
