Hello Ritesh,
Maybe there is something I'm not aware of, but is there any reason why
the pthread_attr_destroy() call occurs twice in this patch instead of
invoking it before the "if (rc) {" statement ? From the
pthread_attr_destroy() man page: "Destroying a thread attributes object
has no effect on threads that were created using that object".
Thanks,
Bart.
