static bool eq_int_type( int_type c1, int_type c2 );		(constexpr since C++11) (noexcept since C++11)

Checks whether two values of type int_type are equal.

See CharTraits for the general requirements on character traits for X::eq_int_type.

Parameters

c1, c2

-

values to compare

Return value

true if c1 is equal to c2, false otherwise.

Complexity

Constant.
