Compare a basic_const_iterator
with another value. These function templates are used when the left operand is not a basic_const_iterator
.
I satisfies the exposition-only concept /*not-a-const-iterator*/ if and only if it's not a specialization of basic_const_iterator
.
These functions are not visible to ordinary unqualified or qualified lookup, and can only be found by argument-dependent lookup when basic_const_iterator<Iter> is an associated class of the arguments.

[edit] Parameters
x, y | - | iterators to compare |
[edit] Return value
[edit] Notes
If the left operand is a basic_const_iterator
, the member comparison functions are used.
[edit] Example
#include <iterator> int main() { static int arr[1]; static constexpr std::basic_const_iterator<int*> it = std::end(arr); static_assert(arr < it); }
