How to make random numbers in a while loop independent from each other?

I have a randomly generated number in a while loop. Since I seed it using time(NULL) when I run it I get a stream of similar results, while I would like it to be more "heterogeneous".

Here's the function:

while(1) {
    srand((unsigned int) time(NULL));   // Seed
    double chance = random() / (double) RAND_MAX;
    if (chance <= 0.95)
        printf("All ok.\n");
    else
        printf("ERROR\n");
}

For example the result of this would look like:

...
All ok.
All ok.
All ok.
All ok.
All ok.
ERROR
ERROR
ERROR
ERROR
ERROR
All ok.
All ok.
All ok.
All ok.
All ok.
...

How can I make the results be more independent from each other?
