get_next

This function combines next with get_name and get_value.

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

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

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

Parameters:

this	a MenuLinkIter
out_link	the name of the link
value	the linked MenuModel

Returns:

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