ab8500_load..._bat_voltage(9)

💅 ab8500_load..._bat_voltage(9) — Kernel API Manual 🎀

okay so bestie, this is a page straight out of the Kernel API Manual, and it's about one very specific little function that goes and gets you a load-compensated battery voltage. yes, that's a whole thing. let's get into it ✨

---

✨ NAME ✨

ab8500_load_comp_fg_bat_voltage — get load compensated battery voltage 🦋

---

🌸 SYNOPSIS 🌸

int ab8500_load_comp_fg_bat_voltage (struct ab8500_fg *di , bool always );

---

💖 ARGUMENTS 💖

• di — pointer to the ab8500_fg structure. that's your main character right there 👑
• always — always return a voltage, also uncompensated. like, even if the compensated one isn't available, you still get a number 🔥

---

🧚 DESCRIPTION 🧚

Returns compensated battery voltage (on success) else error code. slay 💅

If always is specified, we always return a voltage — but heads up, it may be uncompensated. so like, you get a value, it's just maybe not the fancy load-compensated one. lowkey important distinction, no cap 🙈
