Hello,

I'm trying to generate a sequence of random numbers, so I wrote a simple
program to generate 20 random numbers as a test.  I'm using the
srandom() function with a seed value generated by rawclock().  I thought
this might be a good way to generate a different seed every time. 
However, rawclock() seems to be returning zero every time, which causes
me to get the same sequence of random numbers every time.  Can anyone
offer any suggestions on what I'm doing wrong or alternate methods?  I'm
using Windows NT4--perhaps that has something to do with it?  Short code
follows.

Thanks,

Jason Cain

#include <stdio.h>

int main() {
        int c, seed;

        seed = rawclock();
        srandom(seed);

        printf ("Seed value:  %d\n", seed);
        for(c=0; c < 20; c++)
          printf("Random number:  %d\n", random());

        return 0;
}
