ipc_init_ids(9)

💅 ipc_init_ids — like, the kernel API manual page, bestie

okay so this is ipc_init_ids(9) from the Kernel API Manual and honestly? it's giving "small function, big responsibilities." it's a <void> function, it takes one arg, and it sets up the whole identifier situation for System V IPC. no cap. 🎀

---

✨ NAME ✨

ipc_init_ids — initialise ipc identifiers 🦋

like, it literally initialises the ipc identifiers. that's the whole vibe. that's the job.

---

🌸 SYNOPSIS 🌸

void ipc_init_ids (struct ipc_ids *ids );

that's it. that's the signature. void in, void out, one pointer of chaos in the middle. 💜

---

🫶 ARGUMENTS 🫶

• ids — the ipc identifier set 💅 this is the thing getting set up, bestie. it's the ipc identifier set, which is exactly what it sounds like and also somehow more.

---

🔥 DESCRIPTION 🔥

okay so picture this: ipc_init_ids sets up the sequence range to use for the ipc identifier range — and yes, that range is limited below ipc_mni, which is a real detail, i'm not making that up, that's literally what it says. 📏✨

then, once that's handled, it initialises two things:

1. the keys hashtable 🗝️
2. the ids idr 🆔

and that's the whole function. no drama, no extra steps, no secret third thing. it just does the setup so the rest of the ipc machinery has somewhere to live. main character energy for a setup function, honestly. 👑

ngl if you're editing anything under ./ipc you're gonna want at least four of these open in other tabs. that's not a technical claim, that's just me knowing the vibe. 😭

✨ cute sign-off time ✨

this little beauty lives in the ./ipc section and the page is dated October 2026. that's the source and the date, right there, wrapped in a bow 🎀💖 go forth and initialise those identifiers, iykyk 💅
