OK heres the deal see, I'm playing around with C++'s rand functions n' such, When I decide I want to make a dice rolling sim. here is what I have:

Code:
/******************************************

int RandInt(int a, int b){
    return a + rand() % (b - a + 1);
}

int d4(int iNumbr){
    for ( true;iNumbr;iNumbr--){
                    srand(unsigned(time(NULL)));
                    iTotal += RandInt(1,4);
    }

I keep getting a Linker Error, like the one below :::
