2010年2月23日 · In RAII, holding a resource is a class invariant, and is tied to object lifetime: resource allocation (or acquisition) is done during object creation (specifically initialization), by the constructor, while resource deallocation (release) is done during object destruction (specifically finalization), by the destructor.

2014年4月22日 · RAII, Resource Acquisition Is Initialization means that all acquired resources should be acquired in the context of the initialization of an object. This forbids "naked" resource acquisition.

2008年12月27日 · In practice with C++, what is RAII, what are smart pointers, how are these implemented in a program and what are the benefits of using RAII with smart pointers?

2013年10月17日 · The reference that I personally have found most helpful on the topic of RAII is the book Exceptional C++ by Herb Sutter. Many of the topics covered in that book are touched on in the Guru of the Week articles by Sutter.

Is it possible to implement RAII in pure C? I assume it isn't possible in any sane way, but perhaps is it possible using some kind of dirty trick. Overloading the standard free function comes to ...

2017年1月5日 · I'm wondering, for no other purpose than pure curiosity (because no one SHOULD EVER write code like this!) about how the behavior of RAII meshes with the use of goto (lovely idea isn't it). class ...

2013年6月18日 · I want to write a simple RAII wrapper for OpenGL objects (textures, frame buffers, etc.) I have noticed, that all glGen* and glDelete* functions share the same signature, so my first attempt was like

2012年4月2日 · No and no. using is the closest you can get to RAII (more accurately, we are talking about the resource release that follows a RAII-idiom object being destructed). To answer your points more directly: IDisposable (and by extension using) was created exactly because there is no way to do that in .NET. using is syntactic sugar that gets compiled as try / finally and only requires that the object ...

In C++ the finally is NOT required because of RAII. RAII moves the responsibility of exception safety from the user of the object to the designer (and implementer) of the object. I would argue this is the correct place as you then only need to get exception safety correct once (in the design/implementation).

2013年9月16日 · While in plain C I could use fopen(), fseek(), fread() function combination and read the whole file to a buffer, is it still a good idea to use the same for C++? If yes, then how could I use RAII approach while opening, allocating memory for buffer, reading and reading file content to buffer.
