void luaL_unref (lua_State *L, int t, int ref);
Releases reference ref from the table at index t
(see luaL_ref ).
The entry is removed from the table,
so that the referred object can be collected.
The reference ref is also freed to be used again.
If ref is LUA_NOREF or LUA_REFNIL ,
luaL_unref does nothing. |
