NAME std::wstring_convert<Codecvt,Elem,Wide_alloc,Byte_alloc>::from_bytes – std::wstring_convert<Codecvt,Elem,Wide_alloc,Byte_alloc>::from_bytes Synopsis Defined in header <locale> wide_string from_bytes( char byte ); (1) wide_string from_bytes( const char* ptr ); (2) wide_string from_bytes( const byte_string& str ); (3) wide_string from_bytes( const char* first, const char* last); (4) Performs multibyte to wide conversion, using the codecvt facet supplied at construction. 1) Converts byte as if…

NAME std::wstring_convert<Codecvt,Elem,Wide_alloc,Byte_alloc>::converted – std::wstring_convert<Codecvt,Elem,Wide_alloc,Byte_alloc>::converted Synopsis Defined in header <locale> std::size_t converted() const; (until C++14) std::size_t converted() const noexcept; (since C++14) Returns the number of source characters that were processed by the most recent from_bytes() or to_bytes(). Return value The number of characters consumed by the most recent conversion operation. Example // Run this code   #include…

NAME std::wctomb – std::wctomb Synopsis Defined in header <cstdlib> int wctomb( char *s, wchar_t wc ); Converts a wide character wc to multibyte encoding and stores it (including any shift sequences) in the char array whose first element is pointed to by s. No more than MB_CUR_MAX characters are stored. If wc is the null…

NAME std::wcstombs – std::wcstombs Synopsis Defined in header <cstdlib> std::size_t wcstombs( char* dst, const wchar_t* src, std::size_t len); Converts a sequence of wide characters from the array whose first element is pointed to by src to its narrow multibyte representation that begins in the initial shift state. Converted characters are stored in the successive elements…

NAME std::wcsrtombs – std::wcsrtombs Synopsis Defined in header <cwchar> std::size_t wcsrtombs( char* dst, const wchar_t** src, std::size_t len, std::mbstate_t* ps ); Converts a sequence of wide characters from the array whose first element is pointed to by *src to its narrow multibyte representation that begins in the conversion state described by *ps. If dst is…

NAME std::wbuffer_convert<Codecvt,Elem,Tr>::rdbuf – std::wbuffer_convert<Codecvt,Elem,Tr>::rdbuf Synopsis Defined in header <locale> std::streambuf* rdbuf() const; (1) std::streambuf* rdbuf( std::streambuf* bytebuf ); (2) 1) returns the pointer to the underlying byte stream 2) replaces the associated byte stream with bytebuf . Return value 1) the current underlying byte stream 2) the previous byte stream Example // Run this code…

NAME std::mbtowc – std::mbtowc Synopsis Defined in header <cstdlib> int mbtowc( wchar_t* pwc, const char* s, std::size_t n ); Converts a multibyte character whose first byte is pointed to by s to a wide character, written to *pwc if pwc is not null. If s is a null pointer, resets the global conversion state and…

NAME std::mbrtowc – std::mbrtowc Synopsis Defined in header <cwchar> std::size_t mbrtowc( wchar_t* pwc, const char* s, std::size_t n, std::mbstate_t* ps ); Converts a narrow multibyte character to a wide character. If s is not a null pointer, inspects at most n bytes of the multibyte character string, beginning with the byte pointed to by s…

NAME std::codecvt_byname – std::codecvt_byname Synopsis Defined in header <locale> template< class InternT, class ExternT, class State > class codecvt_byname : public std::codecvt<InternT, ExternT, State>; std::codecvt_byname is a std::codecvt facet which encapsulates multibyte/wide character conversion rules of a locale specified at its construction. Four specializations are provided by the standard library Defined in header <locale> std::codecvt_byname<char,…

NAME std::codecvt<InternT,ExternT,State>::length,do_length – std::codecvt<InternT,ExternT,State>::length,do_length Synopsis Defined in header <locale> public: int length( StateT& state, const ExternT* from, (1) const ExternT* from_end, std::size_t max ) const; protected: virtual int do_length( StateT& state, const ExternT* from, (2) const ExternT* from_end, std::size_t max ) const; 1) public member function, calls the member function do_length of the most derived…

NAME std::codecvt<InternT,ExternT,State>::in,std::codecvt<InternT,ExternT,State>::do_in – std::codecvt<InternT,ExternT,State>::in,std::codecvt<InternT,ExternT,State>::do_in Synopsis Defined in header <locale> public: result in( StateT& state, const ExternT* from, const ExternT* from_end, (1) const ExternT*& from_next, InternT* to, InternT* to_end, InternT*& to_next ) const; protected: virtual result do_in( StateT& state, const ExternT* from, const ExternT* from_end, (2) const ExternT*& from_next, InternT* to, InternT* to_end, InternT*& to_next )…
