event_trigger_parse(9)

📦 version 7.3.1, in nixpkgs unstable

💅 event_trigger_parse(9) — like, the Kernel API Manual one 🎀

okay so bestie, welcome to the group chat for event_trigger_parse(9) ✨ this is the page for the generic event_command @parse implementation, and honestly? it's kind of the main character of trigger parsing 🫶

✨ NAME ✨

event_trigger_parse — the Generic event_command @parse implementation 🌸

🦋 SYNOPSIS 🦋

int event_trigger_parse (struct event_command *cmd_ops , struct
trace_event_file *file , char *glob , char *cmd , char *param_and_filter
);

no cap, that's the whole signature. look at her 💅

🎀 ARGUMENTS 🎀

  • cmd_ops — the command ops, and she's the one who handles the trigger registration 👑
  • file — the trace_event_file that's hanging out with this event 🦋
  • glob — the raw string you used to register the trigger, straight up, unfiltered, literally 🙈
  • cmd — the cmd portion of the string used to register the trigger ⭐
  • param_and_filter — the param and filter portion of the string used to register the trigger; yes bestie, both of them, together, iconic 🍓

🌈 DESCRIPTION 🌈

this is the common implementation for event command parsing and trigger instantiation ✨ it's the shared, reusable version — the one everybody borrows 😌

usually it gets used directly as the parse method in event command implementations. like, no wrapper, no middleman, she's just built for it 💅

🔥 RETURN 🔥

0 on success, errno otherwise — that's it, that's the vibe check ✅

lowkey reminder: non-zero means something went sideways, and the value is an errno code 🫶

💖 SEE ALSO 💖

kernel file ./kernel/trace/trace_events_trigger.c — go read it, it's giving source-code realness 📖

and then the whole friend group, fr fr:

like, the whole squad showed up 🌸💜

alright bestie, that's the page — brought to you from ./kernel/trace, dated October 2026, and yeah, it's event_trigger_parse(9) all the way down 😭💅✨ mwah! 🫶
