Is boost::is_iequal supposed to work only with chars?

[simmo.saan@…]

While trying to use it to compare 2 std::strings I couldn't get it to work - I got std::bad_casts. Looking at the source code revealed that it used std::toupper which just uppercases a single char. Is it supposed to work like this or what?

Hello,

As the documentation states, is_iequal is "element" or "character" comparison predicate. As so it is used as a plugin to more complext algorithms that are using it for atomic operations on elements of a string.

If you'd like to compare strings, you can use lexicographical_compare algorithm.
