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 it was a…

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.

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…
