If write is successful, it is performed atomically. The data written must be naturally aligned.
p The .Nm routines provide the following functionality: l -tag -width "suswintr()" t Fn subyte Stores a byte of data to the user-space address
a base . t Fn suword Stores a word of data to the user-space address
a base . t Fn suword16 Stores 16 bits of data to the user-space address
a base . t Fn suword32 Stores 32 bits of data to the user-space address
a base . t Fn suword64 Stores 64 bits of data to the user-space address
a base . t Fn suswintr Stores a short word of data to the user-space address
a base . This function is safe to call during an interrupt context. .El .Sh RETURN VALUES The .Nm functions return 0 on success or -1 on failure. .Sh SEE ALSO .Xr copy 9 , .Xr fetch 9
