read_scratchpad(9)

🎀 read_scratchpad(9) 🎀

okay bestie, welcome to the Kernel API Manual, section 9 — this is the page for read_scratchpad, and it's literally the "go get the actual numbers out of the device RAM" girlie. no cap. 💅

---

✨ NAME ✨

read_scratchpad — read the data in device RAM 🌸

---

🦋 SYNOPSIS 🦋

int read_scratchpad (struct w1_slave *sl , struct therm_info *info );

---

💖 ARGUMENTS 💖

• sl — pointer to the slave to read. that's your 1-Wire bestie, the one you're pulling data from 🫶
• info — pointer to a structure to store the read results. it's giving "bring your own container", you hand her somewhere to put the goods 📦✨

---

🔥 RETURN 🔥

0 if success, -kernel error code otherwise. so like, zero is the slay outcome, and anything else is a negative kernel error code being dramatic at you 😭

main character energy only: you're reading device RAM, not guessing at it. if the return value isn't 0, something's off and the kernel is telling you so ✨
