Objects of this class are created before all of the standard extractors are run. It is responsible for exception-safe prefix and suffix operations, although only prefix actions are currently required by the standard. Definition at line 638 of file istream.

Constructor &; Destructor Documentation template<typename _CharT, typename _Traits> std::basic_istream< _CharT, _Traits >::sentry::sentry (basic_istream< _CharT, _Traits > &__is, bool__noskipws = false) [explicit] The constructor performs all the work. Parameters: is The input stream to guard. noskipws Whether to consume whitespace or not. If the stream state is good (is.good() is true), then the following actions are performed, otherwise the sentry state is false (not okay) and failbit is set in the stream state. The sentry's preparatory actions are: 1. if the stream is tied to an output stream, is.tie()->flush() is called to synchronize the output sequence 2. if noskipws is false, and ios_base::skipws is set in is.flags(), the sentry extracts and discards whitespace characters from the stream. The currently imbued locale is used to determine whether each character is whitespace. If the stream state is still good, then the sentry state becomes true (okay).
