why aren't comparators passed as refs or c-refs in algorithms? Hello if you take for example: template<class ForwardIterator, class Compare> ForwardIterator min_element(ForwardIterator first, ForwardIterator last, Compare comp); I am curious why hasn't been chosen to be passed as: template<class ForwardIterator, class Compare> ForwardIterator min_element(ForwardIterat... 29 Jul 2010 08:34

What are requirements for allocator destructor? In Dinkumware's reference, I found the following example: === For example, given an allocator object al of type A, you can allocate an object of type Other with the expression: A::rebind<Other>::other(al).allocate(1, (Other *)0) === I have written a pooled memory allocator that satisfies the std::allocator ... 19 Jul 2010 15:44

Is comparison of doubles stable? Hi, This is somewhat tricky question: - we have two doubles d1 and d2 - and d1 < d2 Is it guaranteed (and where exactly in C++/IEEE 754 standards?) that this relationship will stay if I move d1 and/or d2 around in memory? I'll try to illustrate this in example: double foo() { ... } // this is a "generato... 21 Jul 2010 19:07
UTF-8 messages in exceptions ? Hello I need to write some wrapper classes around a library that my client has, and the error messages (and all the other strings in the library) are in UTF-8. Can I somehow create an exception class derived from std::exception (std::runtime_error) that could carry such messages ? I mean the message returned s... 25 Jul 2010 19:26
anonymous namespace and C linkage I require a function which must have a C linkage specification (it is a callback from a C library) to be a friend of a class in order to have access to protected member functions of the class: it forms part of the class implementation. Because it has to be a friend it must be declared in the class header file prov... 25 Jul 2010 09:43 |
