The function returns
true if either the
failbit or the
badbit is set. At least one of these flags is set when some error other than reaching the End-Of-File occurs during an input operation.
failbit is generally set by an input operation when the error was related with the internal logic of the operation itself, while
badbit is generally set when the error involves the loss of integrity of the stream, which is likely to persist even if a different operation is performed on the stream.
badbit can be checked independently by calling member function
bad.
Parameters
none
Return Value
true if
badbit and/or
