gpiod_get_array(9)

💖 NAME 💖

okay bestie, this is gpiod_get_array(9) from the Kernel API Manual — the page for grabbing a whole squad of GPIOs at once, like a group-chat invite for pins 🫶✨

gpiod_get_array — obtain multiple GPIOs from a multi-index GPIO function. it's giving "one function, many descriptors" energy 💅

---

✨ SYNOPSIS ✨

struct gpio_descs * gpiod_get_array (struct device *dev , const char
       *con_id , enum gpiod_flags flags );

---

🎀 ARGUMENTS 🎀

• dev — the GPIO consumer 🫶 can be NULL for system-global GPIOs.
• con_id — the function within the GPIO consumer ✨
• flags — optional GPIO initialization flags 🎀

---

🌸 DESCRIPTION 🌸

This function acquires all the GPIOs defined under a given function. not me showing up with one function and leaving with the entire GPIO squad 😭💅

---

🦋 RETURN 🦋

you get back the GPIO descriptors corresponding to the function con_id of device dev ✨

if no GPIO has been assigned to the requested function, it's -ENOENT 😭

or you get another IS_ERR code if an error occurred while trying to acquire the GPIOs 💀
