luaW_tounit_ptr()

unit_ptr luaW_tounit_ptr	(	lua_State *	L,
		int	index,
		bool	only_on_map
	)

Similar to luaW_tounit but returns a unit_ptr; use this instead of luaW_tounit when using an api that needs unit_ptr.

luaW_tounit_ref()

lua_unit* luaW_tounit_ref	(	lua_State *	L,
		int	index
	)

Similar to luaW_tounit but returns a lua_unit; use this if you need to handle map and recall units differently, for example.

Note that this only returns null if the element on the stack was not a unit, so it may be an invalid unit.
