tb_switch_find_by_route(9)

hiii bestie 💖 welcome to tb_switch_find_by_route(9) from the Kernel API Manual — manual name folded in near the top like a little bow 🎀

🌸 NAME 🌸

tb_switch_find_by_route — Find switch by route string. that's it, that's the mission, and it's lowkey iconic 💅

✨ SYNOPSIS ✨

struct tb_switch * tb_switch_find_by_route (struct tb *tb , u64 route );

🎀 ARGUMENTS 🎀

• tb — the domain the switch belongs to. 🫶
• route — the route string to look for. 🔍

💅 DESCRIPTION 💅

okay so here's the tea: the returned switch has its reference count increased 😭 so the caller needs to call tb_switch_put when done with the switch. that's not optional, bestie — it's literally the rule. periodt. 💖

🔥 RETURN 🔥

Pointer to struct tb_switch, or NULL if not found. simple as that, no cap ✨
