auxtrace_record__init(9)

💅 auxtrace_record__init(9) 💅

okay so bestie, welcome to the Kernel API Manual page for auxtrace_record__init(9) — yes the name is long, no cap, but it's literally the init vibe for an AUX area tracing record. 🦋

✨ NAME ✨

auxtrace_record__init — Initialize an AUX area tracing record. 💖

🌸 SYNOPSIS 🌸

struct auxtrace_record * auxtrace_record__init (struct evlist *evlist ,
       int *err );

🎀 ARGUMENTS 🎀

• evlist — the list of events to check for AUX area tracing event. 👀
• err — pointer to an integer to store return code. 🫶

🧚 DESCRIPTION 🧚

So this function looks through the evlist to determine which AUX area tracing hardware is being used, and then it initializes the auxtrace_record structure. That's the whole main-character move. ✨

🔥 RETURN 🔥

• a) A pointer to the struct auxtrace_record with err = 0 on success. Slay. 💅
• b) NULL with err = 0 if no AUX area tracing event is found/supported — and bestie, that is not considered an error. 🙈
• c) NULL with non-zero err on actual auxtrace_record__init failure. That's the real "oof" case. 😭

💜 SEE ALSO 💜

• Kernel file ./tools/perf/util/auxtrace.c and struct auxtrace_cache(9).
