std::char_traits<CharT>::eq_int_type
< 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.
