memset doesn't set an int value.

DESCRIPTION
       The  memset()  function  fills  the  first  n  bytes of the memory area
       pointed to by s with the constant byte c.

It sets a byte value.  K&R just happened to choose 'int' as the type
to store that "unsigned char" in.  Probably for very good reasons which
make absolutely no sense today.
