regulator_get_current_limit(9)

✨ regulator_get_current_limit(9) ✨

okay so bestie, welcome to the Kernel API Manual corner of the group chat 💖. Today’s main character is regulator_get_current_limit(9), and yes she is here to get regulator output current. Slay.

💖 NAME 💖

regulator_get_current_limit — get regulator output current. That’s the whole name vibe, no cap.

🌸 SYNOPSIS 🌸

int regulator_get_current_limit (struct regulator *regulator );

✨ ARGUMENTS ✨

• regulator — regulator source. That’s the thing you’re passing in, bestie 🫶.

🎀 RETURN 🎀

It returns the current supplied by the specified current sink in uA, or a negative error number on failure 😭. So yes: happy path gives you microamps, sad path gives you a negative error number.

🦋 NOTE 🦋

Heads-up, gorgeous: if the regulator is disabled it will return the current value. This function should not be used to determine regulator state — it is not giving state-inspector energy, okay? 💅
