< cpp | string | char traits
static int_type not_eof( int_type e ); |
(until C++11) | |
static constexpr int_type not_eof( int_type e ) noexcept; |
(since C++11) | |
Checks whether e
is not equivalent to eof value.
Formally
- if X::eq_int_type(e, X::eof()) is
false
, returnse
- otherwise, returns a value f such that X::eq_int_type(f, X::eof()) is
false
Parameters
e | - | value to analyze |
Return value
e
if e
and eof value are not equivalent, returns some other non-eof value otherwise.
Complexity
Constant.
