✨ event_trigger_register(9) ✨

okay so bestie, we're in the Kernel API Manual today and this one is literally <pink>event_trigger_register</pink> — the glow-up moment where an event trigger gets officially registered 💅

🌸 NAME 🌸

event_trigger_register — register an event trigger 🎀

🦋 SYNOPSIS 🦋

int event_trigger_register (struct event_command *cmd_ops , struct
trace_event_file *file , char *glob , struct event_trigger_data
*trigger_data );

💖 ARGUMENTS 💖

  • cmd_ops — the event_command operations for the trigger. this is the whole vibe, the operation set that makes the trigger do its thing ✨
  • file — the event file for the trigger's event. the actual location, no cap 📍
  • glob — the trigger command string, and yes it can have the optional remove(!) operator. the <hotpink>!</hotpink> is giving "actually bestie, take it back" energy 🙈
  • trigger_data — the trigger_data for the trigger. the payload, the main character data itself 👑

🌈 DESCRIPTION 🌈

Register an event trigger. simple as that, periodt ✨

the way it works is the cmd_ops are used to call the cmd_ops->reg function, and that's the one that actually does the registration. so event_trigger_register is kind of the icon, the manager, the one who makes the call — but cmd_ops->reg is backstage doing the real work 🫶 lowkey teamwork

⭐ RETURN ⭐

  • 0 on success 🎉
  • errno otherwise 😭 (you know how it is)
