sel_netport_find(9)

💅 sel_netport_find(9) — like, the port-lookup queen 👑

okay so bestie, welcome to the Kernel API Manual ✨ (that's the manual name, we're saying hi to it early, mwah). This is sel_netport_find(9) and honestly? She's short, she's sweet, she does exactly one thing and does it flawlessly. Main character energy fr fr 🎀

---

🌸 NAME 🌸

sel_netport_find — Search for a port record 🔍

No cap, that's the whole gig. She searches. She finds (maybe). Iconic.

---

✨ SYNOPSIS ✨

struct sel_netport * sel_netport_find (u8 protocol , u16 pnum );

Look at that signature. Immaculate. Two args, one pointer back, no drama 💅

---

🦋 ARGUMENTS 🦋

• protocol — the protocol, bestie. That's it, that's the arg 🫶
• pnum — the port 🌸

(Yeah the originals are terse, but we're keeping every word of the meaning: protocol is the protocol and pnum is the port. Nothing invented, nothing dropped. iykyk 😭)

---

💖 DESCRIPTION 💖

So what she actually does: sel_netport_find searches the network port table and returns the matching record. That's the vibe check — you hand her a protocol and a port, she goes digging in the table, and if your entry is there? Slay. She returns it. 👑

But listen — and this is the important part — if an entry can not be found in the table, she returns NULL. Not an error code, not a sad little struct, just NULL. So like... check for that. Always check for that. Not me being dramatic, it's literally in the spec 💀
