     ssuuiibbyyttee(useraddrt addr, int byte);

     int
     ssuuwwoorrdd(useraddrt addr, int word);

     int
     ssuuiiwwoorrdd(useraddrt addr, int word);

     int

     int
     ssuuuulloonngg(useraddrt addr, uint64t longword);

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

     The ssttoorree routines provide the following functionality:

     ssuubbyyttee()   Stores a byte of data to the user-space address addr.

     ssuuiibbyyttee()  Stores a byte of data to the user-space address addr.  This
                function is safe to call during an interrupt context.

     ssuuwwoorrdd()   Stores a word of data to the user-space address addr.

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

     ssuulloonngg()   Stores a long word of data to the user-space address addr.

     ssuuuulloonngg()  Stores a unsigned long word of data to the user-space address
                addr.

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