Another suggestion if you would like to improve the code, is below,
You can move "global_fds[lcore_id]"  check to immediate after  the line

"fds.fd = global_fds[lcore_id]; "
Hi, thanks Pattan.
But I think "global_fds[lcore_id]"  check may move before the line
"fds.fd = global_fds[lcore_id];
If it failed, "fds.fd = global_fds[lcore_id];" should not be performed.
What's your opinion?

That is correct.  You can do that change.
