std::char_traits<CharT>::eq_int_type

From cppreference.com
< cpp‎ | string‎ | char traits
static bool eq_int_type( int_type c1, int_type c2 );
(until C++11)
static constexpr bool eq_int_type( int_type c1, int_type c2 ) noexcept;
(since C++11)

Checks whether two values of type int_type are equal.

Formally,

  • if there exist values a and b such that c1 == X::to_int_type(a) and c2 == X::to_int_type(b), yields the same as X::eq(a,b)
  • otherwise, if c1 and c2 are both copies of X::eof(), yields true
  • otherwise, if one of c1 and c2 is a copy of X::eof() and the other is not, yields false
  • otherwise, the result is unspecified

Parameters

c1, c2 - values to compare

Return value

true if c1 is equal to c2 under the rules described above, false otherwise.

Complexity

Constant.
