C++: "look at what others must do to mimic a fraction of my power"

This is cute, but also I'm baffled as to why you would want to use macros to emulate c++. Nothing is stopping you from writing c-like c++ if that's what you like style wise.

Nice toy. It works until it stops working. An experienced C developer would quickly find a bunch of corner cases where this just doesn't work.

Given how simple examples in this blog post are, I ask myself, why don't we already have something like that as a part of the standard instead of a bunch of one-off personal, bug-ridden implementations?

Just don't mix that up with the real safec.h header from safeclib:

I don't understand this passion for turning C into what it's not...

Just don't use C for sending astronauts in space. Simple.

C wasn't designed to be safe, it was designed so you don't have to write in assembly.

Just a quick look through this and it just shows one thing: someone else's walled garden of hell.
