PAPI_get_real_usec(3)

okay so bestie, welcome to the PAPI manual page for PAPI_get_real_usec(3) 💅 — yes, the real time counter one.

✨ NAME ✨

PAPI_get_real_usec — get real time counter value in microseconds 🕰️✨

🌸 SYNOPSIS 🌸

There isn’t a separate prototype line pasted here; the page rolls straight into the detailed description, and that’s the vibe. 🫶

💖 Detailed Description 💖

okay so this function returns the total real time that has passed since some arbitrary starting point. The time is returned in microseconds ⏱️. This call is equivalent to wall clock time — literally the clock-on-the-wall vibe, no cap. 🕰️

🎀 Examples 🎀

The original example is this exact snippet — copy it character for character, bestie, and do not “fix” it on me 💀:

s = PAPI_get_real_cyc();
your_slow_code();
e = PAPI_get_real_cyc();
printf("Wallclock cycles: %lld\en",e-s);

Yes, the snippet says PAPI_get_real_cyc() even though this page is PAPI_get_real_usec; that’s exactly what the original shows. 👀
