NAME
     store, subyte, suibyte, suword, suiword, sulong, suulong -- store data to
     user-space

SYNOPSIS

     int
     subyte(useraddrt addr, int byte);

     int
     suibyte(useraddrt addr, int byte);

     int
     suword(useraddrt addr, int word);

     int
     suiword(useraddrt addr, int word);

     int
     sulong(useraddrt addr, int64t longword);

     int
     suulong(useraddrt addr, uint64t longword);

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 addr.

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

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

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

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

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

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