Is "fd" a single fd? If so you need to pass this as &fd of course...
The FDSTORE=1 line doesn't need to be suffixed with "\n" btw (but it
doesn't hurt if you do...)
It might be worth strace'ing your process to see that the right
sendmsg() call is issued. If in doubt, strace this specific code
snippet and paste the sendmsg() line here.
