DESCRIPTION
Return -ENODEV if not available on the hardware found. Return 0 if no interesting state in this thread. Return >0 number of size units of interesting state. Any get call fetching state beyond that number will see the default initialization state for this data, so a caller that knows what the default state is need not copy it all out. This call is optional; the pointer is NULL if there is no inexpensive check to yield a value < n.
