There's no difference between receiving an alarm that was sent via alarm or via kill. What makes you think that the latter can trigger signals when the former can't?

What's obfuscated about sending a signal with kill, whose very purpose is to send signals?

    I didn't say that there was a difference. I explained very clearly how to use the alarm signal in a normal application. A signal is a "message" from the OS.

    What's obfuscated about sending a signal with kill, whose very purpose is to send signals?

    What is obfuscated is this "poetry" idea and using language constructs in "unnatural ways". I have no problem with strange code as an art form.

      I didn't say that there was a difference.

      It looks like I misunderstood you.

      there is no way to "safely" continue executing a process after an ALRM signal because many OS functions are not [...] even re-startable by any means.

      What gives you that idea?

      What is obfuscated is this "poetry" idea

      Again, how is kill ALRM, $$ obfuscation/poetry?
