YAMI4 - Messaging Solution for Distributed Systems
I am pleased to announce the availability of version 1.0.0 of the YAMI4 library: YAMI4 is a messaging solution for distributed systems. Typical uses of this library include control and monitoring systems, with real-time and embedded installations, where reliability, performanc... 1 Mar 2010 17:34
Operator chaining
I have a class A which overloads + operator; I am confused about the order of evaluation in the following expression A a,b,c,d; d = a + b + c; how is the right hand side of the expression evaluated. Is a+b performed first or b+c performed first? Thanks for any help. -- [ See http://www.gotw... 2 Mar 2010 14:38
chapter and verse needed for matching new[] to delete[]
I am familiar with the need to match new[] to delete[]. It is a programming error to say new[] then say delet without the square brackets. In some environments this can lead to heap corruption, as Meyers warns in item 5 of Effective C++. What I am looking for is chapter in verse in the std that says this is wron... 1 Mar 2010 17:34
Converting new [] to vectors
I am currently working on some legacy software, and I tend to replace calls to new/delete with auto_ptrs and new[]/delete[] with vectors ... but how do I implement the following whist maintaining RAII, is there a std method of doing this? float (* coords)[3] = NULL; .... long numPoints = sourceOfPoin... 4 Mar 2010 15:46
Unknown syntax - Template parameter void(void)
Hi everyone, I came across a syntax that I haven't seen before, and I can't work out what it means. Hoping someone can help me because I just have to know. template <typename T = void(void)> class Foo { }; I've compiled it now under Microsoft Visual C++ and GNU C++ (under MingW). Unfortunately, I don... 27 Feb 2010 02:21
std::vector<char> instead of std::string, where are the string searching functions?
I am working with some legacy code that is in the process of changing to use std::vector<char> instead of a C-style char array. The C-style char array is currently allocated using new char [n]. This array is passed to various C string functions such as strstr, strncmp etc. I need to do the same work but with a std:... 27 Feb 2010 15:26

Best practice for maintaining an internal reference/pointer to another class
Sal wrote: Imagine you have two classes, ClassA, and ClassB. ClassA is just some class that changes its internal state from time to time, and ClassB is a class that provides additional content, based on the current state of a ClassA instance [...] class ClassA; class ClassB { ClassA ... 26 Feb 2010 08:30
Best practice for maintaining an internal reference/pointer to another class
Alright, so I've been working on a monitoring class for a little while now and I realized that the way I am maintaining my internal references to the monitored class may not be the most obvious to users. Perhaps let me explain how I am doing it now, and then I'd be welcome to suggestions to alternative approaches. ... 26 Feb 2010 18:40
exact difference between C style and static_cast, const_cast
O wise and powerful clcm, What's the precise difference between C style casts, and static_cast. I've always been told that static_cast and const_cast casts are better, but I'd like to know exactly in what circumstances they differ so I can make that judgement myself. Giving me a reference to something in the C... 26 Feb 2010 18:40
