💅 pldm_parse_components(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ — yes this is a real page from the kernel docs and yes we're gonna get through it together. it's about pldm_parse_components and honestly? it's giving "small function, big job" energy. 🎀

---

🌸 NAME 🌸

pldm_parse_components — locate the CRC header checksum 🦋

like literally its whole personality is finding the checksum. that's the job. slay. 💅

---

✨ SYNOPSIS ✨

int pldm_parse_components (struct pldmfw_priv *data );

no cap, that's the whole signature. one argument, one int coming back. simple queen behavior. 👑

---

🫶 ARGUMENTS 🫶

• data — pointer to private data 💜 (that's it, that's the whole description, the original is very much a woman of few words here and we respect it)

---

🔥 DESCRIPTION 🔥

okay so this is where it gets good. here's the whole vibe:

it extracts the component count, and finds the pointer to the component area. 📍

then it scans through each component searching for the end — and that end should point to the package header checksum. 👀 like it's literally walking the whole list until it finds where it stops, iykyk.

then it extracts the package header CRC and saves it for verification. 💾✨ gotta keep it around so somebody can check it later. responsible icon behavior, honestly.

---

⭐ RETURN ⭐

• zero on success 🎉
• a negative error code on failure 😭💀

that's it. zero = we ate. negative = we did not eat.
