💖 Linux::FD 💖

okay bestie, so this is Linux::FD — the Linux-specific special filehandles situation. it's a Perl module, it lives in the User Contributed Perl Documentation section, and the manual page is Linux::FD(3pm). yes we're fancy. 💅

✨ VERSION ✨

this is version 0.017. iconic number, no notes.

🦋 DESCRIPTION 🦋

so here's the vibe: Linux::FD gives you Linux-specific special file handles. that's literally the whole personality. these are:

  • Event filehandles 🎀
  • Signal filehandles 🌸
  • Timer filehandles ⏰

and the reason they slay is that they let you use conventional polling mechanisms to wait for a whole big variety of events. like, you just poll. that's it. that's the trick. the way that works is genuinely so satisfying fr fr. 🫶

🧚 FUNCTIONS 🧚

eventfd($initial_value, @flags) 💫

this one creates an eventfd handle. if you wanna know more about it, go read Linux::FD::Event — it's got the whole lore. 📖

signalfd($sigset) 🦋

this one creates a signalfd handle. more details live in Linux::FD::Signal, so go peek at that. ✨

timerfd($clock_id) ⏰

and this one creates a timerfd handle. the deep dive is in Linux::FD::Timer if you're feeling curious. 🌈
