for_each_interface(9)

💅 for_each_interface(9) — Kernel API Manual 💅

Okay bestie, gather round 🫶. This is the Kernel API Manual page for for_each_interface(9), and it's literally the group-chat message that tells you how to loop over interfaces while the wiphy mutex is held. Slay.

💖 NAME

for_each_interface — iterate interfaces under wiphy mutex.

🛠️ SYNOPSIS

for_each_interface (vif , hw , flags );

🎀 ARGUMENTS

• vif — the iterator variable. It's the one doing the loop-de-loop, bestie.
• hw — the HW to iterate for. The hardware in question. Periodt.
• flags — the iteration flags; see enum ieee80211_interface_iteration_flags for the whole vibe.
