Update: https://cse.usf.edu/~kchriste/tools/udpClientNonblock.c[^] Pretty much what I needed. Yay.
Update 2: Much ado about nothing. Easier than I thought. Docs are just terrible.
Anyone remember the sockets layer from C and C++?
Seriously, the fact that someone actually designed them the way that they did, and it made its way through a standards committee just floors me. The blocking stuff is fine, but the non blocking stuff is incomprehensible, at least last time I looked at it.
It's absolutely the worst asynchronous API I've ever encountered.
I'm about ready to use them in blocking mode on a spawned thread just to avoid it, but the MCU doesn't have a lot of resources and threads are relatively expensive.

I'd be curious to hear more specifically what is wrong about the asynchronous socket API. What is the incomprehensible part.
Communication is, in its very nature, asynchronous. So an asynchronous socket API should be the natural way to do it. Synchronous communication is a straitjacket; you can't work or think freely if you have to force yourself into a synchronous framework for communication.
Religious freedom is the freedom to say that two plus two make five.

It's anything but natural.
Adding, I took a liberty here. I'm using non-blocking and asynchronous interchangeably, but they may not always be in every context.

Works for us. We use blocking sockets for both hardware and inter-process communication. It separates threading concerns from communication concerns.

Separating I/O threads from application threads is an excellent strategy. The I/O threads just do recvfrom/recv and queue messages as work for the application threads. When no message is waiting for an I/O thread, it's easiest to just let it block (with a timeout if it also has other things to do, like freeing TCP sockets that applications released after the I/O thread last blocked).

If I wasn't working on a system with a very primitive scheduler and a miserly amount of RAM I would have seriously considered it. It *did* cross my mind.
But in the end I got it to work without doing so, and it was actually a bit easier than the documentation seemed to suggest. Helped that I found example code.

I can't be the only one that occasionally runs into a situation where I need to produce an awful lot of code before I can test any of it, because it's all interdependent. This often happens when I'm integrating something to an external API that itself is rather complicated, but it can come up in other situations as well. My SVG renderer for example - there are just so many moving interlocking parts that you're standing on a mountain of code before you even get to proof of life.
So if you've ever been in that situation, I imagine you hate it as much as I do.
It's stressful to me. I do not like coding a house of cards, and then having to go back and verify it after the fact. It feels shady. How do you deal with it?
Some kind of process management?
Some clever form of testing I'm not familiar with?

Rarely, but it's a PITA and I get pretty stressed. Usually for nothing but occasionally it proves to be a can of worms and I have to go back and try to debug the code, which causes more frustration until I get to the point where I post a stupid question here on CP that makes no sense to anyone but me then I get away from it for a while and behold I figure it out.
If you can't find time to do it right the first time, how are you going to find time to do it again?

1:Limit and validate input before attempting to process any further logic.
2:Handle any out of bounds input and/or dependency failures with effective error handling and comprehensive logging to allow forensics to show how and why the error was thrown and the inputs or dependency that caused it.
3:make sure the functionality of the new logic is well documented for allowable inputs, desired outputs, snf dependencies, with stakeholders responsible for the requirements well documented so there is no ambiguity about who wanted what, why, and when.
If for whatever reason you can't do all of those in your work, something is very wrong with the overall approach and you are in deep doo-doo.
I had to code "add-on" features and funcitonality to 3rd party business critical enterprise apps many times. 1,2, and 3 made it possible to do so with minimal stress because the proposed logic could be matched to what stakeholders agreed it was supposed to do (except for defects I created in the logic of course which is my own fault).

I'm trying to wrap my head around how that would work in my present situation, and nope. I am not clever enough to figure out how that would help me.

It's my usual way of working, whether coding something big from scratch or making a large change. The benefit is not having to plan stable waypoints that can be tested, which typically involves developing some code that will later disappear. The drawback is anticipating [blecch] several lengthy debug sessions when the code is done.

I don't have a debugger, so the debug sessions are .. interesting.

Hmm, I feel your pain. Complex code, varied data related interactions and no debugger.
In the past, I have integrated a logging function into the code. Usually as a compile time option so I don't have to dismantle it by hand (which I have had to do in the past when compile time options were not available). Usually start with simple module enter/exit logs and then progress to adding inputs and outputs and interesting working variables as the testing progresses. Had to make sure the log function opened, wrote log message and closed the log file to ensure the integrity of the log file should the application die rather than simply producing nonsense output.
