pdc_pat_pd_...form_counter(9)

✨ NAME ✨

Okay bestie, this is the pdc_pat_pd_...form_counter(9) page from the Kernel API Manual, and it's here to do one iconic thing: pdc_pat_pd_get_platform_counter — retrieve the address of a free-running 64-bit counter. That's the whole assignment, no cap. 🎀

💅 SYNOPSIS 💅

int pdc_pat_pd_get_platform_counter (uint64_t **addr , unsigned long
*freq , unsigned long *unique );

Like, it hands back an int, and you pass it these three argument besties:

🌸 ARGUMENTS 🌸

• addr — the address of the 64-bit counter. That's literally what it is. 💖
• freq — the frequency of the counter, or -1 if unknown. So if nobody knows the frequency, it's giving -1 energy. 🙈
• unique — the big question: although monotonic growing, may it return the same number twice? That's the vibe check this argument is asking about. 👑
