return all the values in a function

This is probably an easy one but my brain is fried from all this. For the function below i want to return all the rocks that are equal to 2 and not just the first one. This just prints the first rock thats equal to 2 it finds. Thanks in advance

void view_drilled_rocks()
{
    int i;
    for (i=0;i<totalRocks;i++){
        if (rocks[i].rock_completed==2){
                printf("Rock No.  Geoligist  Drill(Y/N)    Due date or comp date\n");
                printf("%d \t   %s  \t %d  \t%s", rocks[i].rock_rover_number, rocks[i].geoligist, rocks[i].rock_completed , rocks[i].due_date);
            return 0;
        }
    }

}
