gpiotools_sets(9)

✨ NAME ✨

okay so bestie, meet gpiotools_sets(9), straight outta the Kernel API Manual, and its whole job is literally Set values to specific lines. 🎀 no cap, that's the vibe.

💅 SYNOPSIS 💅

here's the exact summoning spell, character for character:

int gpiotools_sets (const char *device_name , unsigned int *lines ,
       unsigned int num_lines , unsigned int *values );

🫶 ARGUMENTS 🫶

• device_name — the name of the gpiochip, but without the prefix "/dev/", like "gpiochip0". yep, leave that prefix at home. 💅
• lines — an array of desired lines, specified by offset index for the associated GPIO device. the lines bestie, in array form. ✨
• num_lines — the number of lines to request. count 'em, queen. 👑
• values — the array of values set to gpiochip; it must be 0(low) or 1(high). no secret third option, okay? 😭

🌈 RETURN 🌈

• On success: return 0. slay. ✅
• On failure: return the errno. not the cute kind of plot twist, but noted. 💀
