irdma_ah_exists(9)

🦋 irdma_ah_exists — straight outta the irdma_ah_exists(9) Kernel API Manual

okay so bestie, this page is a short one and honestly? it's giving ✨minimalist icon✨. one job, one function, zero notes. let's get into it 💅

---

🌸 NAME

irdma_ah_exists — check for existing identical AH 🫶

like, "do we already have one of these AHs or not" — that's the entire plot, no subplot, no side quest.

---

🎀 SYNOPSIS

bool irdma_ah_exists (struct irdma_device *iwdev , struct irdma_ah
*new_ah );

yep that's it. it hands you back a bool. no cap 🌈

---

✨ ARGUMENTS

• iwdev — the irdma device 💖
• new_ah — the AH to check for 👑

two args, that's the whole lineup. main character energy from both of them ngl 🎀

---

🔥 DESCRIPTION

returns true if AH is found, false if not found 🦋

that's the entire description. i told you it was a short one 😭 lowkey obsessed with how little it needs to say. vibe check: passed, answer: boolean, periodt 💅
