pldm_first_desc_tlv(9)

💖 NAME 💖

pldm_first_desc_tlv — and bestie, I'm gonna be so real with you, the official description here is literally blank. Empty. Nothing. The manpage author said "the name says it all" and clocked out 😭 so we're just gonna have to find out what it does together. It lives in section 9 of the Kernel API Manual, iykyk.

---

✨ SYNOPSIS ✨

pldm_first_desc_tlv (start );

(yes, that's the exact spacing, don't come for me, I copy-paste faithfully 💅)

---

🎀 ARGUMENTS 🎀

• start — the byte offset of the start of the descriptor TLVs, like, the address where the descriptor party kicks off 🎉

---

🦋 DESCRIPTION 🦋

Okay so here's the whole vibe: you hand it start, which is an offset — just a number, a position in the byte stream, lowkey not that useful on its own ngl — and it converts that starting offset of the descriptor TLVs into an actual pointer to the first descriptor. So you go from "the number 42-ish" to "a real thing you can dereference." It's giving glow-up. It's giving offset-to-pointer pipeline. Obsessed 🫶

That's genuinely the entire function. Small but iconic, main character energy in like four lines of C. Periodt 💜

Every first / next / for_each trio you could ever need, no cap 🔥
