I can’t understand how to use msgsend and msgrecv to send file descriptors to the child process. How do I fill in struct msghdr and struct cmsghdr for this to work?

What research have you done and what have you tried? – kaylum Mar 23 '20 at 22:07
What are `msgsend` and `msgrecv`? Do you mean `sendmsg` and `recvmsg` instead? – Mar 23 '20 at 22:18
