std::basic_stringstream::rdbuf – std::basic_stringstream::rdbuf Synopsis std::basic_stringbuf<CharT, Traits, Allocator> *rdbuf() const; Returns pointer to the underlying raw string device object. Parameters (none) Return value Pointer to the underlying raw string device. Example This section is incomplete Reason: no example
std::basic_stringstream::operator= – std::basic_stringstream::operator= Synopsis basic_stringstream& operator=( basic_stringstream&& other ); (since C++11) Move assigns the string stream other to *this, effectively move-assigning both the std::basic_iostream base class and the associated std::basic_stringbuf. Note that the base class move assignment swaps all stream state variables (except for rdbuf) between *this and other. Parameters other – string stream to…

std::wstring_convert<Codecvt,Elem,Wide_alloc,Byte_alloc>::~wstring_convert – std::wstring_convert<Codecvt,Elem,Wide_alloc,Byte_alloc>::~wstring_convert Synopsis ~wstring_convert(); Destroys the wstring_convert object and deletes the pointer to the conversion facet. Notes Some implementations are able to delete any facet, including the locale-specific facets with protected destructors. Other implementations require the facet to have a public destructor, similar to the the locale-independent facets from <codecvt>. This is LWG_issue_721 Example…

It includes and provides access to 1) The controlled character sequence, also called the buffer, which may contain input sequence (also called get area) for buffering…
std::wscanf,std::fwscanf,std::swscanf – std::wscanf,std::fwscanf,std::swscanf Synopsis Defined in header <cwchar> int wscanf( const wchar_t* format, … ); (1) int fwscanf( std::FILE* stream, const wchar_t* format, … ); (2) int swscanf( const wchar_t* buffer, const wchar_t* format, … ); (3) Reads data from the a variety of sources, interprets it according to format and stores the results into…
std::ws – std::ws Synopsis Defined in header <istream> template< class CharT, class Traits > std::basic_istream<CharT,Traits>& ws( std::basic_istream<CharT, Traits>& is ); Discards leading whitespace from an input stream. Behaves as an UnformattedInputFunction, except that is.gcount() is not modified. After constructing and checking the sentry object, extracts characters from the stream and discards them until any one…
std::basic_regex – std::basic_regex Synopsis Defined in header <regex> template < class CharT, (since C++11) class Traits = std::regex_traits<CharT> > class basic_regex; The class template basic_regex provides a general framework for holding regular expressions. Several specializations for common character types are provided: Defined in header <regex> Type Definition regex basic_regex<char> wregex basic_regex<wchar_t> Member types Member type…
std::basic_ostringstream::swap – std::basic_ostringstream::swap Synopsis void swap(basic_ostringstream &other); (since C++ 11) Exchanges the state of the stream with those of other. This is done by callingbasic_ostream<CharT, Traits>::swap(other) and rdbuf()->swap(*other.rdbuf()). Parameters other – stream to exchange the state with Return value (none) Example This section is incomplete Reason: no example See also operator= moves the string stream…
std::basic_ostringstream::rdbuf – std::basic_ostringstream::rdbuf Synopsis std::basic_stringbuf<CharT, Traits, Allocator> *rdbuf() const; Returns pointer to the underlying raw string device object. Parameters (none) Return value Pointer to the underlying raw string device. Example This section is incomplete Reason: no example
std::basic_ostringstream::operator= – std::basic_ostringstream::operator= Synopsis basic_ostringstream& operator=( basic_ostringstream&& other ); (since C++11) Move assigns the string stream other to *this, effectively move-assigning both the std::basic_ostream base class and the associated std::basic_stringbuf. Note that the base class move assignment swaps all stream state variables (except for rdbuf) between *this and other. Parameters other – string stream to…
std::basic_ostringstream – std::basic_ostringstream Synopsis Defined in header <sstream> template< class CharT, (until C++11) class Traits = std::char_traits<CharT> > class basic_ostringstream; template< class CharT, class Traits = std::char_traits<CharT>, (since C++11) class Allocator = std::allocator<CharT> > class basic_ostringstream; The class template std::basic_ostringstream implements output operations on memory (std::basic_string) based streams. It essentially wraps a raw string device…
std::basic_ostream – std::basic_ostream Synopsis Defined in header <ostream> template< class CharT, class Traits = std::char_traits<CharT> > class basic_ostream : virtual public std::basic_ios<CharT, Traits> The class template basic_ostream provides support for high level output operations on character streams. The supported operations include formatted output (e.g. integer values) and unformatted output (e.g. raw characters and character arrays)….
std::basic_ofstream – std::basic_ofstream Synopsis Defined in header <fstream> template< class CharT, class Traits = std::char_traits<CharT> > class basic_ofstream : public std::basic_ostream<CharT, Traits> The class template basic_ofstream implements high-level output operations on file based streams.

std::wmemset – std::wmemset Synopsis Defined in header <cwchar> wchar_t* wmemset( wchar_t* dest, wchar_t ch, std::size_t count ); Copies the wide character ch into each of the first count wide characters of the wide character array pointed to by dest. If overflow occurs, the behavior is undefined. If count is zero, the function does nothing. Parameters…
std::wmemmove – std::wmemmove Synopsis Defined in header<cwchar> wchar_t *wmemmove(wchar_t *dest, const wchar_t *src, std::size_t count); Copies exactly count successive wide characters from the wide character array pointed to by src to the wide character array pointed to by dest.
