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

SYNOPSIS
     #include <sys/types.h>
     #include <sys/time.h>
     #include <sys/systm.h>
     #include <sys/resourcevar.h>

     int
     subyte(user_addr_t addr, int byte);

     int
     suibyte(user_addr_t addr, int byte);

     int
     suiword(user_addr_t addr, int word);

     int
     sulong(user_addr_t addr, int64_t longword);

     int
     suulong(user_addr_t addr, uint64_t longword);

     int
     suword(user_addr_t addr, int word);

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.

     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.

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

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