get_next

This function combines next with get_name and get_value.

First the iterator is advanced to the next (possibly first) attribute. If that fails, then false is returned and there are no other effects.

If successful, name and value are set to the name and value of the attribute that has just been advanced to. At this point, get_name and get_value will return the same values again.

The value returned in name remains valid for as long as the iterator remains at the current position. The value returned in value must be unreffed using g_variant_unref when it is no longer in use.

Parameters:

this	a MenuAttributeIter
out_name	the type of the attribute
value	the attribute value

Returns:

true on success, or false if there is no additional attribute
