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
.
c | - | value to convert |
A value equivalent to c
.
Constant.
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
.
