The type is an enumerated type T2 that describes an object that can store stream state information. The distinct flag values are:
- badbit, to record a loss of integrity of the stream buffer
- eofbit, to record end-of-file while extracting from a stream
- failbit, to record a failure to extract a valid field from a stream
In addition, a useful value is:
- goodbit, no bits set
