RES: RES: C++ Typecast - so far newbie question

["SosCpdTerra" <soscpd@...>]

What are you talking about? I cannot pass this return value to a variable
and typecast into whatever I want? I guess this is the evil!!

Like:

I have this
void figureout(char *what, int ever)

and I must his 2 args came from lua. Im trying to do this:

int serial(lua_State *L) //my registered function
    {
        int argc = lua_gettop(L);
        const char var1 = lua_tostring(L, 1);
        int var2 = int(lua_tonumber(L, 2));
        figureout(var1, var2);
        return 0;
    }

There is another way? I can't see that way, and that is my problem.

Strings returned by lua_tostring *must not be modified*.

So don't cast them to char* or evil things will happen.
