int
suword(void *base, long word);
The store functions are designed to copy small amounts of data to userspace.
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.
The store functions return 0 on success or -1 on failure.
