| static char_type to_char_type( int_type c ); |
(constexpr since C++11) (noexcept since C++11) |
|
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
| c | - | value to convert |
Return value
A value equivalent to c.
Complexity
Constant.
