perf_cpu_map__new_any_cpu(9)

✨ perf_cpu_map__new_any_cpu ✨

okay so bestie, welcome to the perf_cpu_map__new_any_cpu(9) page from the Kernel API Manual 💅 this one is short and sweet and honestly kind of iconic for it.

---

🎀 NAME 🎀

perf_cpu_map__new_any_cpu — it hands you a map with a singular "any CPU" / dummy -1 value. that's it. that's the whole vibe. one (1) special little dummy entry, no cap 💀

---

🌸 SYNOPSIS 🌸

LIBPERF_API struct perf_cpu_map * perf_cpu_map__new_any_cpu (void );

literally just LIBPERF_API struct perf_cpu_map * perf_cpu_map__new_any_cpu (void ); — copy it exactly, she's perfect 🫶

---

🦋 ARGUMENTS 🦋

• void — no arguments. none. zero. the void is voiding 🙈 nothing to pass, nothing to worry about, just call her and go ✨

ngl this is the lowkey dream signature — you can't mess up the args if there are no args 💖
