il_queue_inc_wrap(9)

💅 il_queue_inc_wrap(9) — a Kernel API Manual moment

okay so bestie, welcome to the Kernel API Manual entry for il_queue_inc_wrap(9) ✨ this is a lil function from the kernel API docs and she is, and I cannot stress this enough, extremely small and extremely specific 🎀

---

🌸 NAME 🌸

il_queue_inc_wrap — increments the queue idx and wraps back to the beginning 🌀

so like, the full description in the original is literally: increment queue idx, wrap back to beginning @idx -- current idx @n_bd -- total number of entries in queue (must be power of 2) 💖

breaking that down for you:

• @idx — your current idx, bestie
• @n_bd — the total number of entries in the queue
• and yes, that n_bd total must be a power of 2 👑 that's not a vibe suggestion, that's the actual rule, no cap

---

✨ SYNOPSIS ✨

int il_queue_inc_wrap (int idx , int n_bd );

look at her. two ints in, one int out. she's giving minimalism 🦋

---

🫶 ARGUMENTS 🫶

• idx — -- undescribed -- 😭 the docs really said "figure it out yourself"
• n_bd — -- undescribed -- 🙈 same energy, no description provided

bestie I need you to know I'm not gatekeeping anything here — the manual genuinely does not describe these two params. the source said -- undescribed -- and I'm just the messenger 💀 and remember, from the NAME section: n_bd is the total number of entries in the queue and it must be a power of 2 ⭐

🦋 SEE ALSO 🦋

✨ the kernel file is ./drivers/net/wireless/intel/iwlegacy/common.h — that's where she lives, iykyk 💜
