DESCRIPTION
     The store functions are designed to copy small amounts of data to user-space.

     The store routines provide the following functionality:

     subyte()	 Stores a byte of data to the user-space address base.

     susword()	 Stores a short word of data to the user-space address base.

     suswintr()  Stores a short word of data to the user-space address base.  This function is safe to call during an interrupt context.

     suword()	 Stores a word of data to the user-space address base.

RETURN VALUES
     The store functions return 0 on success or -1 on failure.
