✨ NAME ✨

gpiotools_set — literally sets a value to a specific line. That's the whole vibe, bestie: set value to specific line. 🎀

⚡ SYNOPSIS ⚡

int gpiotools_set (const char *device_name , unsigned int line ,
       unsigned int value );

Okay so that's the exact signature, no cap. 🫶

🌸 ARGUMENTS 🌸

• device_name — the name of the gpiochip, without the prefix /dev/, like "gpiochip0". 🙈
• line — the number of the line, like 2. ✨
• value — the value of the gpio, and it must be 0(low) or 1(high). 💀 That's not a maybe, bestie.

🫶 RETURN 🫶

On success, return 0; on failure, return the errno. Periodt. 💅
