Blocking unicast calls

I have a kernel module that acts as a Generic Netlink server. In the
user space I have a daemon which receives Netlink unicast messages from
the kernel module using the libnl library.
What I'd like to know is if it's possible to send a Netlink message in a
blocking manner and to get a direct result back from the daemon? As far
as I understand the Netlink concept it is a bus-like system and thus I'm
not sure if it's possible at all.
Currently my call to send the message to the user space is as follows:
rc = genlmsg_unicast(skb, daemon_pid);
