C99 shim
You can use C++11 or later. Plain C, C++98 and C++03 can work but require you to write a shim. Will add examples on how to do that if there's enough interest.
Can you give guidance (or an example) of this shim layer for C99?
@major0 @clumsy I created a C Runtime for Lambda based on the nice work Marco has done on the cpp-runtime so far. [ Credits are duly given in the readme file 😄]
Still on its early development days but most features work out of the box and even though I mention that any C11 compiler is required in the readme file, I'm almost certain that I don't use anything specific that wouldn't allow you to compile with C99.

Disclaimer: I decided to learn C a few months ago and thought that a Lambda C runtime would be a good pet project for me to start with. Any constructive feedback that can help me improve my C skills is welcome. Hope this pet project of mine helps anyone wanting to run C on lambda 😃
Great job, @PauloMigAlmeida I did the exact same thing you did, with one difference though - I've made it via a single-header library. But around same time I've discovered Rust runtime for lambda which I think is much more robust, safe and has the same performance. This is the reason I decided not to publish my runtime and suggest you give Rust runtime for lambda a try!
@marcomagdy there are two things I think are important:
- Rust itself providing a lot of features to make it safe (without compromising performance for people for whom it's important), and I could not put it better than in this talk
- The fact that this runtime is provided by AWS labs: good chances it will be supported/optimized by the people with good experience in AWS
I hate to digress this thread further but
a) you’re conflating Rust the programming language with the Lambda runtime.
b) The C++ Lambda runtime is also under awslabs just like the Rust runtime.
I was curious if you had more concrete points on why you think the Rust runtime is more robust than the C++ runtime.
@marcomagdy I'm sorry if I was not clear enough. I was comparing my custom C99 non-awslabs lambda runtime with the Rust lambda runtime. My point was about Rust runtime benefiting from the safety features of the language (again, when comparing to my custom C99 non-awslabs runtime). I was never planing on using C++ lambda runtime, let alone comparing it to the Rust lambda runtime (was only here for the C99 shim).
