+ * The following helpers are here to avoid compiler complaints about unchecked

+ * FIXME: The proper fix would be to check the return code in all those places,
+ * but it's usually placed in old code which have no proper exit path and
+ * handling  errors requires rewriting a lot of code.
+ *
+ * WARNING: Please do not use these helpers in new code. Instead, make sure
+ * you check the function return code and provide coherent error handling in
+ * case of error.
