fc_exch_els_rec(9)

💅 fc_exch_els_rec — a whole manual page, bestie

okay so this is a page from the Kernel API Manual, section 9, and it's all about fc_exch_els_rec. yes you read that right, a manpage about the handler for ELS REC (that stands for Read Exchange Concise) requests. it's giving "niche but iconic" and honestly? we love a specialist. 🎀

✨ NAME ✨

fc_exch_els_rec — the handler for ELS REC (Read Exchange Concise) requests. that's it, that's the whole job description, and she does it flawlessly. 👑

---

🌸 SYNOPSIS 🌸

void fc_exch_els_rec (struct fc_frame *rfp );

literally one function, one argument, zero drama. void return, so like… she says nothing back, she just does. main character energy fr fr. 💜

---

🦋 ARGUMENTS 🦋

• rfp — the REC frame itself. and here's the tea, bestie: it is not freed here. so do not go freeing it in your head, do not assume it got cleaned up, it did not. someone else's problem, not hers. note that down. 📝

---

🔥 DESCRIPTION 🔥

okay so the whole vibe here is one extremely important heads-up:

note that the requesting port may be different than the S_ID in the request.

that's it. that's the description. the entire lore. do not just eyeball the S_ID and assume that's the port asking, because it might not be, and you would look goofy. the way that one sentence will save you hours of debugging… iykyk. 😭✨
