regulator_list_voltage(9)

💖 regulator_list_voltage(9) 💖

okay bestie, welcome to the Kernel API Manual — this is the page for regulator_list_voltage(9), and it's literally all about enumerating supported voltages ✨

---

🌸 NAME 🌸

regulator_list_voltage — enumerate supported voltages 💅

---

✨ SYNOPSIS ✨

the whole signature, untouched:

int regulator_list_voltage (struct regulator *regulator , unsigned
       selector );

---

🎀 ARGUMENTS 🎀

• regulator — regulator source 💖 the regulator source you're asking about, bestie.
• selector — identify voltage to list 🦋 the selector that says which voltage we're listing.

---

🧚 CONTEXT 🧚

can sleep 😴 — yeah, this one can sleep, no cap.

---

🔥 RETURN 🔥

it's giving three possible moods:

• the voltage for the selector, and that value can be passed to regulator_set_voltage ⚡
• 0 if the selector can't be used on this system 🙈
• a negative error number on failure 😭
