store, subyte, suword — store data to user-space
Contents
Description
The store 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.
Name
store, subyte, suword — store data to user-space
