ubi_add_av(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’… ubi_add_av β€” like, the whole manual page, bestie

okay so real quick before we dive in: this is from the Kernel API Manual, section 9 (ubi_add_av(9)), and it's a tiny little function but she's important. Let's get into it πŸ’–


✨ NAME ✨

ubi_add_av β€” add volume to the attaching information. that's it. that's the whole job. she adds a volume to the attaching information and she does it flawlessly, no notes πŸ‘‘


πŸ¦‹ SYNOPSIS πŸ¦‹

struct ubi_ainf_volume * ubi_add_av (struct ubi_attach_info *ai , int
vol_id );

so you call her with an attach info struct and a volume id, and she hands you back a struct ubi_ainf_volume *. easy. cute. iconic.


🌸 ARGUMENTS 🌸

  • ai β€” the attaching information. like, the whole context she's working inside. it's giving "main character energy" for the entire attach process πŸ’…
  • vol_id β€” the requested volume ID. the specific volume you want, bestie. no guessing, this is the one you asked for.

πŸŽ€ DESCRIPTION πŸŽ€

so the way that this works is β€” ubi_add_av returns a pointer to the new volume description, or an ERR_PTR if the operation failed 😭

that's literally it. if it slays, you get the pointer. if it doesn't, you get an ERR_PTR and you should absolutely check for that because ignoring error pointers is not the vibe. fr fr. πŸ™ˆ


πŸ”₯ SEE ALSO πŸ”₯

she doesn't work alone okay, this whole squad lives in the kernel file ./drivers/mtd/ubi/attach.c:

like I said. a whole squad. go read them, they're all lowkey fascinating πŸ’œ


okay that's the whole page!! mwah πŸ’‹ this one's brought to you by the fine people at ./drivers/mtd/ubi, dated October 2026 β€” that's the source and the date, periodt, no cap. now go add some volumes, bestie 🫢✨
