💖 Net::W...::Layer 💖

okay bestie, welcome to the Net::W...::Layer manual page, she's part of the User Contributed Perl Documentation and honestly? she's the blueprint 👑

✨ NAME ✨

Net::Write::Layer — base class and constants, no cap 💅

🌸 SYNOPSIS 🌸

use Net::Write::Layer qw(:constants);

that's it. that's the whole entrance. iconic behavior honestly ✨

🦋 DESCRIPTION 🦋

okay so this is the base class for Net::Write::Layer2, Net::Write::Layer3 and Net::Write::Layer4. like, she's the mother of the family 💖

and what does she do? she provides those layers with inheritable attributes, methods and constants. that's literally her whole job. she's giving supportive parent energy, not main character — she lets the kids shine 🫶

💜 ATTRIBUTES 💜

  • dev — the network interface you're using. the lil door your packets walk out of 🚪
  • dst — the target IPv4 or IPv6 address. where the vibes are being sent 📬
  • protocol — the transport layer protocol you want (TCP, UDP, ...). pick your fighter ⚔️
  • family — the adresse family to use (NW_AF_INET, NW_AF_INET6). yes the original says "adresse", we're keeping it, iykyk 🙈

🎀 METHODS 🎀

  • new — the object constructor. returns undef on error. so like, if it hands you nothing back, that's a undef, not a maybe 🫠
  • open — opens the descriptor, for when you are ready to send. returns undef on error. open it when you're actually ready, bestie, not before 💫
  • send (scalar) — sends the raw data passed as a parameter. returns undef on failure, true otherwise. so real ones succeed, and the undef is the flop era 😭
  • close — closes the descriptor. say bye, be polite 👋
  • nw_getsaddr
  • nw_inet_pton — internal functions. not for us, they're doing backstage work, respect the crew 🛠️

💅 CONSTANTS 💅

address family constants — for use with the family attribute 🌈

  • NW_AF_INET
  • NW_AF_INET6
  • NW_AF_UNSPEC
