STORE(9) OpenBSD Kernel Manual STORE(9)
NAME
store - store data to user-space
SYNOPSIS
#include <sys/types.h>
#include <sys/systm.h>
int
subyte(void *base, unsigned char c);
int
susword(void *base, unsigned short s);
int
suswintr(void *base, unsigned short s);
int
suword(void *base, unsigned long l);
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, c, to the user-space address base.
susword() Stores a short word of data, s, to the user-space address
base.
suswintr() Stores a short word of data, s, to the user-space address
base. This function is safe to call during an interrupt con-
text.
suword() Stores a word of data, l, to the user-space address base.
NOTE
The store routines are deprecated. All new code should use copyout().
RETURN VALUES
The store functions return 0 on success or -1 on failure.
