CNXSoft: This is another guest by Blu, this time about C programming, and specifically destructors in C programming language If you asked seasoned C++ developers what their favorite features in the C++ language might be, chances are that destructors would be on everybody’s shortlist. As many other C++ developers, I too tend to do my occasional share of C, and if there’s one feature I dearly miss in C that is destructors ‒ precisely in their capacity of automating the release of resources at the right moment. But first a disclaimer is in order: many people call simple application of destructors ‘RAII’ ‒ ‘Resource Acquisition Is Initialization’; I find this acronym unnecessarily awkward and obfuscating an otherwise straightforward concept, so you won’t see this acronym through the end of this text. Instead, I’ll be using ‘end-of-scope’ action. Traditionally, in the language of C end-of-scope (more often end-of-function) actions are achieved via deliberate arrangement of the control flow, often via goto’s …
