STORE(9)		 BSD Kernel Developer's	Manual		      STORE(9)

NAME
     store, subyte, suword -- store data to user-space

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

     int
     subyte(volatile void *base, int byte);

     int
     suword(volatile void *base, long word);

     int
     suword16(volatile void *base, int word);

     int
     suword32(volatile void *base, int32_t word);

     int
     suword64(volatile void *base, int64_t word);

     #include <sys/resourcevar.h>

DESCRIPTION
     The store functions are designed to copy small amounts of data to user-
     space.  If	write is successful, it	is performed atomically.  The data
     written must be naturally aligned.

     The store routines	provide	the following functionality:

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

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

     suword16()	 Stores	16 bits	of data	to the user-space address base.

     suword32()	 Stores	32 bits	of data	to the user-space address base.

     suword64()	 Stores	64 bits	of data	to the user-space address base.

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