SYNOPSIS
#include <sys/types.h>
#include <sys/time.h>
#include <sys/systm.h>
int
subyte(void *base, int byte);
int
suword(void *base, long word);
int
suword16(void *base, int word);
int
suword32(void *base, int32_t word);
int
suword64(void *base, int64_t word);
#include <sys/resourcevar.h>
int
suswintr(void *base, 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 base.
suword() Stores a word of data to the user-space address base.
suword16() Stores 16 bits of of data to the user-space address base.
suword32() Stores 32 bits of of data to the user-space address base.
suword64() Stores 64 bits of of data to the user-space address base.
suswintr() Stores a short word of data to the user-space address base.
This function is safe to call during an interrupt context.
RETURN VALUES
The store functions return 0 on success or -1 on failure.
