DESCRIPTION

The functions are designed to copy small amounts of data to user-space.

The routines provide the following functionality:

Fn subyte

Stores a byte of data to the user-space address base

Fn suword

Stores a word of data to the user-space address base

Fn suword16

Stores 16 bits of data to the user-space address base

Fn suword32

Stores 32 bits of data to the user-space address base

Fn suword64

Stores 64 bits of data to the user-space address base

Fn 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

The functions return 0 on success or -1 on failure.
