  * A few points:
  *
  * Instead of returning an empty string array or empty uid array, we
  * may return NULL.

+ * Free the data the library returns with libc free(). String arrays
+ * are NULL terminated and you need to free the array itself in
+ * addition to the strings contained.

  * We return error codes as negative errno, kernel-style. 0 or
  * positive on success.
