Then how do I call it, given I find this thing, when in use that there's a pushstring occurring first if I keep searching.

Code:
function lua_error(L : Plua_State) : Integer;
  cdecl; external LuaDLL;
Do I?:
Code:
lua_pushstring(L,'Error!');
lua_error(L);
EDIT:

Found it, LuaUtils.pas. Sorry, should've checked there.
