std::char_traits<CharT>::not_eof: std::char_traits<CharT>::not_eof

NAME

std::char_traits<CharT>::not_eof - std::char_traits<CharT>::not_eof

Synopsis

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, returns e
* 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.
