✨ NAME ✨

HPL_ptimer_walltime — Return the elapsed (wall-clock) time. ⏰

That's it. That's the whole job. She clocks the wall. She's literally just vibing with a stopwatch 🫶

---

🌸 SYNOPSIS 🌸

so here's how you actually summon her:

#include "hpl.h"

double HPL_ptimer_walltime();

yeah she takes no arguments, she just shows up and hands you a double 💅 no cap, that's the entire interface.

🦋 DESCRIPTION 🦋

HPL_ptimer_walltime returns the elapsed (wall-clock) time.

like... that's the assignment and she ate it. ✨ wall-clock time = the actual time that has passed in the real world, not CPU cycles, not vibes, not your feelings about how long the compile took 😭 elapsed, wall-clock, that's the whole personality. she's the friend who tells you how long you've actually been standing in line, not how much energy you expended doing it 💀

no extra options, no hidden flags, no drama. main character energy, minimal API. periodt 🎀

👑 SEE ALSO 👑

go read her besties, they're all linked up:

• HPL_ptimer_cputime (3)
• HPL_ptimer (3)

ngl if you're timing something and you reach for the CPU time instead of the wall time, that's a whole different conversation and it's giving "measured the wrong thing" 🙈 HPL_ptimer_cputime (3) is right there for that.

and that's the page!! 🎀 this little cutie comes to you from HPL 2.2, dated February 24, 2016, and yes she's been serving wall-clock realness since way back and she has never once needed a rewrite. iconic. slay. bye bestie 💜🦋✨
