What type of fd's are these? Regular files? TCP sockets? UDP sockets? Something else? Are these fd's in blocking or non-blocking mode? What kernel are you running? Going under the assumption that these are TCP sockets running under a relatively recent kernel, *yes*, you definitely want to deal with the situation in which sendfile() returns something less than "count".
