< void send(int *to,int *from, int count) {
< int n = (count + 7) / 8;
<
< switch(count % 8) {
< case 0: do { *to++ = *from++;
< case 7: *to++ = *from++;
< case 6: *to++ = *from++;
< case 5: *to++ = *from++;
< case 4: *to++ = *from++;
< case 3: *to++ = *from++;
< case 2: *to++ = *from++;
< case 1: *to++ = *from++;
< } while (--n > 0);
< }
< }
