| static int_type not_eof( int_type e ); |
(constexpr since C++11) (noexcept since C++11) |
|
Given e, produces a suitable value that is not equivalent to eof.
This function is typically used when a value other than eof needs to be returned, such as in implementations of std::basic_streambuf::overflow().
See CharTraits for the general requirements on character traits for X::not_eof.
Parameters
| e | - | value to analyze |
Return value
e if e and eof value are not equivalent, or some other non-eof value otherwise.
Complexity
Constant.
