ldm_parse_vblk(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 ldm_parse_vblk — the kernel API tea, bestie edition 🌸

okay so we're doing ldm_parse_vblk(9) today, from the Kernel API Manual obviously, and honestly? iconic little function. it takes raw VBLK bytes and turns them into a proper vblk struct. let's get into it 💅

✨ NAME ✨

ldm_parse_vblk — read a raw VBLK object into a vblk structure. that's the whole vibe. main character behavior fr 🫶

🦋 SYNOPSIS 🦋

bool ldm_parse_vblk (const u8 *buf , int len , struct vblk *vb );

🎀 ARGUMENTS 🎀

  • buf — block of data being worked on. the raw material, the moment before the glow-up ✨
  • len — size of the block of data. yes bestie, we need to know how much 💖
  • vb — in-memory vblk in which to return information. this is where the info goes to live 🌸

💜 DESCRIPTION 💜

okay so here's what she does: she reads a raw VBLK object into a vblk structure. that's it, that's the whole job 💅

lowkey the way it works is she handles the information that's common to all VBLK types first — the shared stuff everyone's got, the group-chat basics 🫶 — and then she delegates the rest of the work to helper functions: ldm_parse_*. like, she's not doing everything herself, she's a team player, she hands off the specialized bits to the specialists. no cap, that's good delegation energy 👑

👑 RETURN 👑

this section is literally empty in the original. like, genuinely nothing here. not me pointing at an empty section 🙈 — but i promised to keep every detail, and the detail is that there are no return details. going with it. slay.

🌈 SEE ALSO 🌈

kernel file ./block/partitions/ldm.c — that's the source of truth, the mothership, the origin story 🧚

and now the whole ldm extended universe, because she does not exist in a vacuum:

twenty-eight of them. TWENTY-EIGHT. she's got a whole friend group and every single one of them is linked above, i did not skip a single one because i would never 😭💖

okay that's the page! no warnings, no bug notes, no exit statuses here — this one's a clean little parser function and honestly we love that for her 🌸

and that's a wrap, bestie 🎀 this one came from the ./block/partitions corner of the kernel, dated October 2026 — so like, future girl summer energy fr fr. ldm_parse_vblk(9), out. periodt 💅✨
