DESCRIPTION
Thestore functions are designed to copy small amounts
of data to user-space. If write is successful, it is performed atomically. The
data written must be naturally aligned.
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.
RETURN VALUES
The store functions return 0 on success or
-1 on failure.
