cm32181_read_als_it(9)

🌸 NAME 🌸

okay so bestie, we're flipping through the Kernel API Manual and the main character here is cm32181_read_als_it(9) — it’s literally the function that does Get sensor integration time (ms). no cap, that’s the whole vibe. 💅

✨ SYNOPSIS ✨

int cm32181_read_als_it (struct cm32181_chip *cm32181 , int *val2 );

🎀 ARGUMENTS 🎀

• cm32181 — pointer of struct cm32181. it’s the sensor’s little backstage pass. 🫶
• val2 — pointer of int to load the als_it value. yes, it’s where the answer gets dropped off. 💖

🦋 DESCRIPTION 🦋

it reports the current integration time in milliseconds. that’s it, that’s the tea. it’s giving “just tell me the integration time, bestie” energy, and honestly? iconic. ✨

🔥 RETURN 🔥

if everything slays, you get IIO_VAL_INT_PLUS_MICRO. otherwise? -EINVAL. periodt. 💀
