ios_base::iostate

typedef T2 iostate;
static const iostate badbit, eofbit, failbit, goodbit;

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
