That's what luaL_dofile does. If result is not 0, then the error message
is at the top of the stack and can b retrieved with lua_tostring(L,-1).

Thanks for pointing me in the right direction, such a simple solution once you know how ;-)
For other newbee wondering about this, the follow code works just fine:
if (luaL_dofile(L, "frame.lua")!=0)
{
printf("Error: %s\n",lua_tostring(L,-1));
}
