Re: luaL_where

["Patrick Donnelly" <batrick.donnelly@...>]

lbaselib.c (for the error() function) uses luaL_where:

static int luaB_error (lua_State *L) {
  int level = luaL_optint(L, 2, 1);
  lua_settop(L, 1);
  if (lua_isstring(L, 1) && level > 0) {  /* add extra information? */
    luaL_where(L, level);
    lua_pushvalue(L, 1);
    lua_concat(L, 2);
  }
  return lua_error(L);
}

You can see how the "chunkname:linenumber: errormsg" is generated :)

Cheers,
