+ *
+ * After successful initialization the flag <PREFIX>_DEBUG_INIT is always set
+ * to the mask (this flag is required). The <PREFIX> is usually library API

+ *
+ * where for the FOO has to be defined <PREFIX>_DEBUG_FOO.
+ *
+ * It's possible to initialize the mask by comma delimited strings with
+ * subsystem names (e.g. "LIBMOUNT_DEBUG=options,tab"). In this case is
+ * necessary to define mask names array. This functionality is optional.
+ *
+ * It's strongly recommended to use UL_* macros to define/declare/use

+ *
+ * See disk-utils/cfdisk.c: cfdisk_init_debug() for programs debug
