I would rather use bool or an enum for the return status instead of this int.
The default set affinity operation should accept only CPU sets that specify the
complete set of available processors, e.g. for a three processor system it
should be bits 0, 1, and 2 set, all other bits cleared (e.g. (1 << CPU count) - 1).
The default get affinity operation should return the CPU sets reflecting all
available processors.
