+ * specified by 'cpuset'.
+ *
+ * @param thread_id
+ *    Id of the thread for which to set the affinity.
+ *
+ * @param cpuset
+ *   Pointer to CPU affinity to set.
+ *
+ * @return
+ *   On success, return 0.
+ *   On failure, return a positive errno-style error number.

Usually we return negative numbers on error.
