Process does not properly handle SIGINT

[storm roost]

I am trying to get a process to ignore SIGINT. I have set the handler to an empty function, but the program still ends when I press CTRL+C. I put a call to puts inside the handler and it was executed. exit is not being called anywhere so I do not think that it makes sense that my program is ending. Here is some code that illustrates very basically what my program is doing. I can show more if necessary: https://pastebin.com/0vD5TseN

Depending on your machine this might actually be impossible as Ctrl + C doesn't necessarily produce any specific signal or any signal at all for that matter.

However there's a SO post which demonstrates a few solutions: https://stackoverflow.com/questions/4217037/catch-ctrl-c-in-c

If it doesn't produce any signal, then how does it terminate the process?

No clue.
I simply summarized a comment on the SO post:

There's no such thing as catching signals in C.... or at least so I thought until I read the C99 standard. It turns out that there is signal handling defined in C but Ctrl-C isn't mandated to produce any specific signal or a signal at all. Depending on your platform, this might be impossible.

But upon researching I couldn't find anything else, besides someone who said that Ctrl + C could also send SIGTERM.

...And upon even further research it appears that that's apparently only for customly configured terminals.

I'll look at it once I get home in case noone else answers.

Thank you. You've been a huge help.

Actually, the signal catching worked several weeks ago.

Recently it has stopped working though.
