Net::W...Layer4(3pm)

✨ Net::Write::Layer4 ✨

okay bestie, gather round 💖 this is Net::Write::Layer4 from the User Contributed Perl Documentation, and it's giving transport layer descriptor energy. layer 4. the big leagues. we're sending raw data over the network and we're doing it with our whole chest 🫶

---

🌸 NAME 🌸

Net::Write::Layer4 — it's an object for a transport layer (layer 4) descriptor. that's it, that's the whole vibe.

---

🎀 SYNOPSIS 🎀

here's the whole thing in action, copy it exactly, no cap:

use Net::Write::Layer qw(:constants);
use Net::Write::Layer4;

my $desc = Net::Write::Layer4->new(
   dst      => '192.168.0.1',
   protocol => NW_IPPROTO_TCP,
   family   => NW_AF_INET,
);

$desc->open;
$desc->send('G'x666);
$desc->close;

look at her. open, send, close. a whole little lifecycle arc 😭✨ iconic.

---

💅 DESCRIPTION 💅

so basically: this is the class for creating a layer 4 descriptor. that's the tea. that's what she does. periodt.

---

🦋 ATTRIBUTES 🦋

• dst — the target IPv4 or IPv6 address that we're gonna send frames to. like, where the packets are going, bestie 📬
• family — the address family. for the full list of options, go peek at the CONSTANTS section of Net::Write::Layer.
• protocol — which transport layer protocol we're using. again, the CONSTANTS section of Net::Write::Layer has the whole menu 🍓

---

⭐ METHODS ⭐

• new — the object constructor, obviously 💅. you MUST pass a valid dst attribute, no skipping that, she will not work without it. the default values are:
  • protocol: NW_IPPROTO_TCP
  • family: NW_AF_INET

and if something goes wrong? it returns undef on error. sad girl hours 😭

• open — opens the interface. returns undef on error.
• send (scalar) — sends raw data to the network. this is the main character moment honestly 🔥
• close — closes the descriptor. bye bestie 👋

---

💀 CAVEATS 💀

okay this one's important. it does not work at all under Win32 systems. like, not even a little. ngl it's because they can't send frames at layer 4. that's just the situation, we don't make the rules 🙈
