functionality:
subyte
()- Stores a byte of data to the user-space address base.
suword
()- Stores a word of data to the user-space address base.
suword16
()- Stores 16 bits of data to the user-space address base.
suword32
()- Stores 32 bits of data to the user-space address base.
suword64
()- Stores 64 bits 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.
RETURN VALUES¶

functions return 0 on success or -1
on failure.
