Or steal one from FreeBSD (written by Paul Saab), fix the err() function
and be done with it.

.../usr.bin/fsync/fsync.{1,c}

Interesting side note -- mind the O_RDONLY:

        for (i = 1; i < argc; ++i) {
                if ((fd = open(argv[i], O_RDONLY)) < 0)
                        err(1, "open %s", argv[i]);

                if (fsync(fd) != 0)
                        err(1, "fsync %s", argv[1]);
                close(fd);
        }
