NAME

     store, subyte, suibyte, susword, suswintr, suword, suiword -- store data
     to user-space


SYNOPSIS

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

     int
     subyte(void *base, int c);

     int
     susword(void *base, short c);

     int
     suswintr(void *base, short c);

     int
     suword(void *base, long c);


DESCRIPTION

     The store functions are designed to copy small amounts of data to the
     user-space of the currently running process.

     The store routines provide the following functionality:

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

     susword()   Stores a short word 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.

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


RETURN VALUES

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