I have been working on a project in my personal time that has nothing at all to do with my main job. I work on it after work, on the trolley to work, and on the trolley from work. I store all my source code in my own personal repository on my personal server in my apartment. While at work, I use the same computer which I purchased to do...
Consider the following class structure: class Filter { virtual void filter() = 0; virtual ~Filter() { } }; class FilterChain : public Filter { FilterChain(collection<Filter*> filters) { // copies "filters" to some internal list // (the pointers are copied, not the filters themselves) } ~Filter...
Gentlement, following situation. There are files in a network share to which even Administrators have no permissions, permissions are set for two individual users only.

Hi all, I have a question regarding shared_ptrs and ownership in C++: I have a bunch of objects created on the heap. Each one has a container which holds pointers to some of these objects, and sometimes, even a pointer to the same object the container belongs to. Since I read about the risks of using shared_ptr under such circumstances...
I have a program that is highly multi-threaded and it contains an intrusive linked list of objects. I need to pass off the objects in this list to several threads, but only 1 thread will ever own the object at a time, meaning that I don't need this object or the pointer to it be shared. I wanted to create an intrusive list with a uniqu...
If I use a container of shared_ptrs and explicitely allow access to its elements, should I return shared_ptrs or raw pointers if I intend the container to be the one responsible for "cleaning up"? class Container { private: std:vector<shared_ptr<Foo> > foo_ptrs; public: shared_ptr<Foo> operator[](std::size_t index) const {}; //...
