    Good hygiene with size_t output argument.
    
    Though the callers check the function return value and ignore the
    size_t output argument on failure, it is still often not ideal to
    store -1 in a size_t on error.  That might signal an unduly large
    buffer.  Instead set the size_t to 0, to indicate no space.
