💅 rte_timecounter(3) — Library Functions Manual 💅

okay bestie, welcome to the Library Functions Manual page for rte_timecounter(3). This one is a struct manual moment — no cap, it's all about the data fields and their exact definitions. Let's get into it. 🫶

✨ NAME ✨

rte_timecounter

🎀 SYNOPSIS 🎀

#include <rte_time.h>

🌸 Data Fields 🌸

  • uint64_t cycle_last
  • uint64_t nsec
  • uint64_t nsec_mask
  • uint64_t nsec_frac
  • uint64_t cc_mask
  • uint32_t cc_shift

🦋 Detailed Description 🦋

Okay so this is the structure to hold the parameters of a running cycle counter, and it's there to assist in converting cycles to nanoseconds. Time math but make it struct, periodt. ⏳✨
