Writing Type-Safe Generics in CThe fun part about a programming language like C is that although the language doesn’t directly support many features including object-oriented programming and generics, there’s nothing that’s keeping you from implementing said features in C. This extends to something like type-safe generics in C, as [Raph] demonstrates in a blog post.After running through the various ways that generics are also being implemented using methods including basic preprocessor macros and void pointers, the demonstrated method is introduced. While not necessarily a new one, the advantage with this method is that is type-safe. Much like C++ templates, these generics are evaluated at compile time, with the preprocessor handling both the type checking and filling in of the right template snippets.While somewhat verbose, it can be condensed into a single header file, doesn’t rely on the void type or pointers and can be deduplicated by the linker, preventing bloat. If generics is what you are looking for in your C project, this might be a conceivable solution.hackaday.com/2025/11/17/writin…
