key_write_idx(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… key_write_idx(9) β€” like, the whole manual, but make it make sense

okay so real talk: this is key_write_idx from the Kernel API Manual (that's the manual name, bestie, we're in the kernel section 🐧), and it's genuinely one of those tiny lil functions that does one job and does it slayfully. no drama, no surprises β€” it just takes a key that's chilling in in-memory format and transforms it into the format the index wants. periodt. πŸ’–


✨ NAME ✨

key_write_idx β€” transform a key from in-memory format for the index. that's it. that's the whole vibe. πŸŽ€


🌸 SYNOPSIS 🌸

void key_write_idx (const struct ubifs_info *c , const union ubifs_key
*from , void *to );

it returns void, so like… don't go looking for a return value, she gives you nothing back and she's iconic for it 🫢


πŸ¦‹ ARGUMENTS πŸ¦‹

  • c β€” the UBIFS file-system description object. your context, your main character, the whole setting of the scene ✨
  • from β€” the key to transform. this is the one getting the glow-up πŸ’…
  • to β€” the key to store the result. this is where the transformed key lands, no cap πŸ“

okay this is the part where the page just. lists everyone. the whole friend group. all of them live in the kernel file ./fs/ubifs/key.h, and honestly the way this roster goes on… it's giving group chat with 33 members and everyone's typing 😭

like?? thirty-three entries. she said "let me introduce you to everybody" and then actually did it πŸ’€ but fr fr, if you're poking around keys in UBIFS, this is your reading list and every single one of them is right there in ./fs/ubifs/key.h 🧚


ngl there's no RETURN VALUE section and no ERRORS section here β€” the function is void, so there's literally nothing coming back. don't manifest a return code that isn't in the source, bestie πŸ™ˆ
