DESCRIPTION
The store functions are designed to copy small amounts of data to user-space.The store routines provide the following 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.
