✨ gpiochip_fwd...get_multiple(9) ✨

okay so bestie, this is a page straight out of the Kernel API Manual and it's literally about gpiochip_fwd_gpio_get_multiple — like the function that grabs values for multiple GPIO forwarder lines at once. no cap, it's giving efficiency queen energy 👑💅

🌸 NAME 🌸

gpiochip_fwd_gpio_get_multiple — Get values for multiple GPIO forwarder lines 🦋

🎀 SYNOPSIS 🎀

int gpiochip_fwd_gpio_get_multiple (struct gpiochip_fwd *fwd , unsigned
long *mask , unsigned long *bits );

literally that's the whole signature, keep it exactly like that bestie, don't touch it 💖

💜 ARGUMENTS 💜

  • fwd — the GPIO forwarder itself. that's your main character right there 🫶
  • mask — a bit mask array, one bit per line, and BITS_PER_LONG bits per word define which lines are gonna get read. so this is the "who's invited to the party" list 👑
  • bits — a bit value array, one bit per line, with BITS_PER_LONG bits per word, and it will contain the read values for the lines that mask specified. so this is where the actual answers land 💅✨

⭐ RETURN ⭐

0 on success, or a negative errno on failure. slay when it's zero, 😭 when it's negative.
