     subyte(void *base, int byte);

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.
