Let's indead consider this example.  This is wrong, wrong, wrong (even
though it may happen to work on your system).  The second argument to
read is a char *, not a structure pointer.  To pass lint (and to have
it work on word-based machines), it should read:

	/* ... */

	while (read(fd, (char *) &person,sizeof(person)) == sizeof(person)) {
		/* ...do something to person structure... */
	}
