At least FreeBSD uses the following:

     int
     sendfile(int fd, int s, off_t offset, size_t nbytes,
         struct sf_hdtr *hdtr, off_t *sbytes, int flags);

which seems remarkably painful ...  Solaris and Linux both
use:

     ssize_t sendfile(int out_fd, int in_fd, off_t *off, size_t len);

Back to that good ol' saying about standards....
