ldm_parse_dgr4(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ldm_parse_dgr4

okay so bestie, we're in the Kernel API Manual today and this one is literally about pulling a raw VBLK Disk Group object into a vblk structure. yes it's as niche as it sounds. no cap. 🎀

✨ SYNOPSIS ✨

bool ldm_parse_dgr4 (const u8 *buffer , int buflen , struct vblk *vb );

like, that's the whole vibe. three args, one bool back. slay. 🦋

🫶 ARGUMENTS 🫶

  • buffer — the block of data we're working on rn. that's it, that's the data. 👑
  • buflen — the size of said block of data. so we don't go wandering off the end like a main character with no impulse control 💀
  • vb — the in-memory vblk where the info gets returned. this is the little container we're filling up, okay? 🍓

🌸 DESCRIPTION 🌸

Read a raw VBLK Disk Group object (version 4 — important, she's specific) into a vblk structure.

that's the whole assignment. dgr4 specifically, version 4 specifically, into vblk specifically. it's giving "small function, very online". ✨

💜 RETURN 💜

okay so... the original page literally leaves this section blank. like, nothing. empty. an icon of restraint honestly 😭 — so I'm not gonna invent a return value for you, bestie, because that would be making stuff up and we don't do that. the synopsis says bool, that's all we've got. respect the mystery 🙈

🌈 SEE ALSO 🌈

Kernel file ./block/partitions/ldm.c — go read the source if you want the real tea ☕

and then the whole ldm friend group, in order, because they all roll together:

like a whole friend group chat and ldm_parse_dgr4 is in there somewhere. iykyk 💅

ngl the dgr3 version is right there next door if you ever need the older sibling. just saying. 👀

mwah 💖 that's the page!! brought to you from the ./block/partitions corner of the kernel, dated October 2026, and yes we're still out here parsing VBLK structures in the future. periodt. 🎀✨
