🎀 gpiod_cansleep(9) 🎀

okay so bestie, this page is from the Kernel API Manual, and the main character is gpiod_cansleep(9). It’s the function that reports whether gpio value access may sleep. lowkey important if you’re poking at GPIO stuff. ✨

✨ NAME ✨

gpiod_cansleep — report whether gpio value access may sleep. 💅

🌈 SYNOPSIS 🌈

int gpiod_cansleep (const struct gpio_desc *desc );

💖 ARGUMENTS 💖

• desc — gpio to check. 👀

🦋 RETURN 🦋

Returns 0 for non-sleepable, 1 for sleepable, or an error code in case of error. That’s the whole return tea — slay. 🍵
