def recvmsg_nonblock(dlen = nil, flags = 0, clen = nil,
                     scm_rights: false, exception: true)
  __recvmsg_nonblock(dlen, flags, clen, scm_rights, exception)
end

recvmsg receives a message using recvmsg(2) system call in non-blocking manner.

It is similar to BasicSocket#recvmsg but non-blocking flag is set before the system call and it doesn’t retry the system call.

By specifying a keyword argument exception to false, you can indicate that recvmsg_nonblock should not raise an IO::WaitReadable exception, but return the symbol :wait_readable instead.
