+The library provides basic function object classes for all of the comparison
+operators in the language ([[expr.rel]](expr.rel "7.6.9 Relational operators"), [[expr.eq]](expr.eq "7.6.10 Equality operators"))[.](#1.sentence-1)

+For templates less, greater, less_equal, andgreater_equal, the specializations for any pointer type
+yield a result consistent with the
+implementation-defined strict total order over pointers ([[defns.order.ptr]](defns.order.ptr "3.28 implementation-defined strict total order over pointers"))[.](#2.sentence-1)

+[*Note [1](#note-1)*:

+If a < b is well-defined
+for pointers a and b of type P,
+then (a < b) == less<P>()(a, b),(a > b) == greater<P>()(a, b), and so forth[.](#2.sentence-2)

+For template specializations less<void>, greater<void>,less_equal<void>, and greater_equal<void>,
+if the call operator calls a built-in operator comparing pointers,
+the call operator yields a result consistent
+with the implementation-defined strict total order over pointers[.](#2.sentence-3)
