If the sequence is empty, eofbit is set in the stream, but not failbit. ![]() This manipulator extracts whitespace characters, stopping when the next character is non-whitespace, or when the input sequence is empty. References basic_ios::_M_setstate(), ios_base::badbit, ios_base::eofbit, ios_base::failbit, ios_base::goodbit, basic_ios::rdbuf(), and basic_ios::setstate(). Otherwise, sets failbit in the input stream.Äefinition at line 1023 of file istream.tcc. After constructing a sentry object with good status, this function extracts a character (if one is available) and stores it in c. References ios_base::badbit, ios_base::eofbit, ios_base::failbit, ios_base::goodbit, and std::max().Ä«ehaves like one of the formatted arithmetic extractors described in std::basic_istream. If no characters are extracted, sets failbit.Äefinition at line 1050 of file istream.tcc. Width(0) is then called for the input stream. the next character is a null byte (i.e., charT() ).the next character is whitespace according to the current locale.otherwise n is "the number of elements of the largest array of char_type that can store a terminating eos." /6Ĭharacters are extracted and stored until one of the following happens: Input stream iosbase ios istream iostream ifstream istringstream Input stream objects can read and interpret input from sequences of characters.if width() is greater than zero, n is width().Prefer: Note: boost::iostreams::copy already does the correct thing. This at least breaks with embedded NUL chars. Not only does it assume the full size of qqq is always read, but also qqq decays from char (&) 500000 to char and will be interpreted as NUL-terminated string. After constructing a sentry object with good status, this function extracts up to n characters and stores them into the array starting at s. Your code in the second function is questionable, where you do. template basic_istream & ws (basic_istream &_in)Ä«ehaves like one of the formatted arithmetic extractors described in std::basic_istream.template basic_istream & operator> (basic_istream &_in, _CharT &_c).template basic_istream & operator> (basic_istream &_in, _CharT *_s). ![]() You should not attempt to use it directly. This is an internal header file, included by other library headers.
