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
suword(user_addr_t addr, int word);
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);

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.
