ldm_parse_privhead(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ldm_parse_privhead — a Kernel API Manual moment 🌸

okay so this is ldm_parse_privhead(9), bestie, and it lives in the Kernel API Manual (yes queen, the big one). it's a little function with one job and honestly? it ate. let's get into it 🎀

✨ NAME ✨

ldm_parse_privhead — Read the LDM Database PRIVHEAD structure 👑

like, that's it. that's the whole vibe. it reads the PRIVHEAD. iconic behavior fr fr.

🦋 SYNOPSIS 🦋

bool ldm_parse_privhead (const u8 *data , struct privhead *ph );

look at that signature. bool return, two args, no notes. she's giving minimalism ✨

🌸 ARGUMENTS 🌸

  • data — the raw database PRIVHEAD structure, freshly loaded from the device 💾 this is the unglamorous raw bytes version, straight off the disk, no filter no edit.
  • ph — the in-memory privhead structure where the parsed info gets dropped off 🫶 it's basically the cute little tote bag you're packing all the parsed goodness into.

💖 DESCRIPTION 💖

so here's the tea: this function parses the LDM database PRIVHEAD structure that you handed it in data, and then it sets up the in-memory privhead structure ph with all the information it just obtained from it. 🧚

that's the whole plot. raw bytes in, tidy in-memory struct out. she's a converter, she's a translator, she's doing the most for you and asking for nothing back. main character energy honestly 💅

🙈 RETURN 🙈

bestie... the original page literally leaves this blank 😭 like, nothing under RETURN. not a single crumb. so i'm not gonna make anything up — no invented return values, no guessing, that's not the move. if you need the deets, go read the source, because this section is giving empty group chat 💀

no cap: when a manpage has an empty section, you respect the empty section. we don't speculate here. 🫡

🔥 SEE ALSO 🔥

the whole LDM squad, and they're all here, so let me introduce the lineup 🎤

the kernel file herself:

  • ./block/partitions/ldm.c

and the extended friend group:

like okay go off, entire LDM subsystem. we see you. we appreciate you. 🫶✨

lowkey a reminder: this whole page is the LDM partition-parsing corner of the kernel, so if you're poking at it, you're already kinda deep. vibe check passed. 👑

and that's the page, babe 💜 it shipped from ./block/partitions, dated October 2026 — mark your calendar bestie, that's the version and the date, right there in the footer, now immortalized in this sign-off instead of a boring last line. mwah. 🎀🦋✨
