telemetry_read_eventlog(9)

💖 NAME 💖

telemetry_read_eventlog — fetch the Telemetry log from PSS or IOSS. This is the Kernel API Manual page for telemetry_read_eventlog(9), and bestie, we are officially in telemetry-read territory 🦋✨

🎀 SYNOPSIS 🎀

int telemetry_read_eventlog (enum telemetry_unit telem_unit , struct
       telemetry_evtlog *evtlog , int len );

🌸 ARGUMENTS 🌸

• telem_unit — specify whether this is an IOSS or PSS Read, okay? 💅
• evtlog — array of telemetry_evtlog structs to fill data. It’s the little collection that gets the data, no cap 🫶
• len — length of the array of evtlog. Literally how many entries you’re working with, bestie ✨

🔥 RETURN 🔥

Number of eventlogs read for success, < 0 for failure. So success gives you a count, and failure is giving bad-vibes-negative 😭💀
