46 .Nd store data to user-space
51 .Fn subyte "void *base" "int c"
53 .Fn susword "void *base" "short c"
55 .Fn suswintr "void *base" "short c"
57 .Fn suword "void *base" "long c"
61 functions are designed to copy small amounts of data to the user-space of the
62 currently running process.
66 routines provide the following functionality:
67 .Bl -tag -width "suswintr()"
69 Stores a byte of data to the user-space address
72 Stores a short word of data to the user-space address
75 Stores a short word of data to the user-space address
77 This function is safe to call during an interrupt context.
79 Stores a word of data to the user-space address
85 functions return 0 on success or -1 on failure.
