gpiod_set_value(9)

🌸 NAME 🌸

okay so bestie, this is gpiod_set_value(9) from the Kernel API Manual, and it’s literally here to assign a gpio's value 💅✨

✨ SYNOPSIS ✨

int gpiod_set_value (struct gpio_desc *desc , int value );

💅 ARGUMENTS 💅

• desc — the gpio whose value will be assigned 🫶
• value — the value to assign 🎀

🦋 DESCRIPTION 🦋

Set the logical value of the GPIO, i.e. taking its ACTIVE_LOW, OPEN_DRAIN and OPEN_SOURCE flags into account. It’s giving “not raw vibes, logical vibes,” and honestly? iconic 💅

This function can be called from contexts where we cannot sleep 😴🚫, and it will complain if the GPIO chip functions potentially sleep. So yeah, no nap time for this one, fr fr.

🎀 RETURN 🎀

0 on success, negative error number on failure. Zero is the slay outcome; a negative number means something went sideways 💀
