std::char_traits<char>::to_int_type, std::char_traits<wchar_t>::to_int_type, std::char_traits<char8_t>::to_int_type, std::char_traits<char16_t>::to_int_type, std::char_traits<char32_t>::to_int_type
static int_type to_int_type( char_type c ); | (constexpr since C++11) (noexcept since C++11) |
Converts c to int_type.
See CharTraits for the general requirements on character traits for X::to_int_type.
Parameters
| c | - | value to convert |
Return value
A value equivalent to c.
Complexity
Constant.
Notes
For every valid value of char_type, there must be a unique value of int_type distinct from eof().
