std::char_traits<char>::to_char_type, std::char_traits<wchar_t>::to_char_type, std::char_traits<char8_t>::to_char_type, std::char_traits<char16_t>::to_char_type, std::char_traits<char32_t>::to_char_type

static char_type to_char_type( int_type c );

static constexpr char_type to_char_type( int_type c ) noexcept;

Converts c to char_type. If there is no equivalent char_type value (such as when c is a copy of the eof() value), the result is unspecified.

See CharTraits for the general requirements on character traits for X::to_char_type.

Parameters

Return value

A value equivalent to c.

Complexity

Constant.
