: Is there a randomize() funtion for DJGPP?  If so
: which Lib is it in?  I keep getting the same #'s
: when I use the random() funtion, and I need
: to randomize the # seed.

I had the same problem, so I made my own.  Here's what I use:

void randomize(void)
{
   int num = (int) time(NULL);
   if (num < 0)
      num = -num;
   srandom( num );
}

// Gets a random integer from 0 to top - 1.
int getRand(int top)
{
   int num = (int) random();
   if (num < 0)
      num = -num;
   return num % top;
}

Hope that helps,

Jason
