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 );
 (until C++11) 
static constexpr int_type to_int_type( char_type c ) 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().
