- * A few points:
- *
- * Instead of returning an empty string array or empty uid array, we
- * may return NULL.
- *
- * Free the data we return with libc free().
- *
- * We return error codes as negative errno, kernel-style. 0 or
- * positive on success.
- *
- * These functions access data in /proc, /sys/fs/cgroup and /run. All
- * of these are virtual file systems, hence the accesses are
- * relatively cheap.
