std::char_traits<CharT>::eq_int_type
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
andb
such thatc1 == X::to_int_type(a)
andc2 == X::to_int_type(b)
, yields the same asX::eq(a,b)
- otherwise, if
c1
andc2
are both copies ofX::eof()
, yields true - otherwise, if one of
c1
andc2
is a copy ofX::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.
