std::char_traits<CharT>::eq_int_type

static bool eq_int_type( int_type c1, int_type c2 );

static constexpr bool eq_int_type( int_type c1, int_type c2 ) noexcept;

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

Return value

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

Complexity

Constant.
