std::char_traits<CharT>::to_int_type: std::char_traits<CharT>::to_int_type

NAME

std::char_traits<CharT>::to_int_type - std::char_traits<CharT>::to_int_type

Synopsis


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 a value of char_type 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(). For example, a common implementation of char_traits<char>::eof() is return -1, and a corresponding valid implementation of char_traits<char>::to_int_type(c) is return (unsigned char)c.
