std::basic_ostream_sentry

std::basic_ostream< _CharT, _Traits >::sentry(3cxx)					       std::basic_ostream< _CharT, _Traits >::sentry(3cxx)

NAME

       std::basic_ostream< _CharT, _Traits >::sentry -

SYNOPSIS

   Public Member Functions
       sentry (basic_ostream< _CharT, _Traits > &__os)
       ~sentry ()
       operator bool () const

Detailed Description
   template<typename _CharT, typename _Traits>class std::basic_ostream< _CharT, _Traits >::sentry
       Performs setup work for output streams.

       Objects of this class are created before all of the standard inserters are run. It is responsible for exception-safe prefix and suffix
       operations.

       Definition at line 379 of file ostream.

Constructor &; Destructor Documentation
   template<typename _CharT, typename _Traits> std::basic_ostream< _CharT, _Traits >::sentry::sentry (basic_ostream< _CharT, _Traits > &__os)
       [explicit]
       The constructor performs preparatory work. Parameters:
	   os The output stream to guard.

       If the stream state is good (os.good() is true), then if the stream is tied to another output stream, is.tie()->flush() is called to
       synchronize the output sequences.

       If the stream state is still good, then the sentry state becomes true (okay).

       Definition at line 49 of file ostream.tcc.

       References std::ios_base::failbit, std::basic_ios< _CharT, _Traits >::good(), std::basic_ios< _CharT, _Traits >::setstate(), and
       std::basic_ios< _CharT, _Traits >::tie().

   template<typename _CharT, typename _Traits> std::basic_ostream< _CharT, _Traits >::sentry::~sentry () [inline]
       Possibly flushes the stream. If ios_base::unitbuf is set in os.flags(), and std::uncaught_exception() is true, the sentry destructor calls
       flush() on the output stream.

       Definition at line 407 of file ostream.

       References std::ios_base::badbit, std::uncaught_exception(), and std::ios_base::unitbuf.

Member Function Documentation
   template<typename _CharT, typename _Traits> std::basic_ostream< _CharT, _Traits >::sentry::operator bool () const [inline],	[explicit]
       Quick status checking. Returns:
	   The sentry state.

       For ease of use, sentries may be converted to booleans. The return value is that of the sentry state (true == okay).
