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.
