The functions are designed to copy small amounts of data from user-space.The routines provide the following functionality:
- Fn fubyte
- Fetches a byte of data from the user-space address base
- Fn fuword
- Fetches a word of data from the user-space address base
- Fn fuword16
- Fetches 16 bits of data from the user-space address base
- Fn fuword32
- Fetches 32 bits of data from the user-space address base
- Fn fuword64
- Fetches 64 bits of data from the user-space address base
- Fn fuswintr
- Fetches a short word of data from the user-space address base This function is safe to call during an interrupt context.
