Not sure whether are referring to my post itself, or the links to Unix signals in it. In any case:
- my post was not even meant to be insightful (if you thought that was the intention) - it was just a small fun one, showing that the current process can kill itself; the added 2 links about signals was just extra info as a starting point (only) for beginners; I am not responsible for the quality of Wikipedia links (1, see 2); I put in a link to a google search for Unix signals too, and finally, caveat lector (2, see 1).
- the article you linked to does not seem complete. Probably no one article can be unless they put in more effort. Even the K&R or K&P (3, 4) section on signal handling in C, talks about certain issues, and why a naive approach may not be okay. And even that was from way back, when signals were a lot simpler, and did not have the sigset, sigaction and other functions that they acquired later ...
