Hello Everyone,
I realized that the call to srand(time(NULL)) in my changes below may be
contributing towards the same bucket being selected. Can you please tell me an
appropriate function ( *main*()/*init*() ) to initialize the pseudo-random
number generator (i.e. srand(time(NULL)))?
Your help will be greatly appreciated.
Thanks!

uint32_t rand_num = 0, sum = 0; const struct ofputil_bucket *bucket = NULL;
const struct list *buckets;
// initialize random seed srand(time(NULL)); // generate a number
number in [1, 10] rand_num = (rand() % 10) + 1;

list_node, buckets) { sum += bucket->weight; if (rand_num <= sum)
{ return bucket; // return this bucket } }
return bucket; // return NULL} _______________________________________________
