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.
