💅 ds1685_write(9) — the kernel API manual page, bestie edition ✨

okay so this is ds1685_write from the Kernel API Manual, and honestly? it's giving "tiny function, big responsibility." it writes a value to an rtc register. that's it. that's the whole vibe. but we're gonna hype it up properly because it deserves it 💖

✨ NAME ✨

ds1685_write — write a value to an rtc register.

like, literally just yeet a byte into a register. no cap. 🎀

🌸 SYNOPSIS 🌸

void ds1685_write (struct ds1685_priv *rtc , int reg , u8 value );

void return. no error code, no "did it work?", no nothing. she just does the thing and leaves. main character energy fr fr 👑

🦋 ARGUMENTS 🦋

  • rtc — pointer to the ds1685_rtc structure. this is your bestie, your context, the whole personality of the chip. hold onto her 🫶
  • reg — the register address to write. where the magic goes. pick wisely 💅
  • value — value to write to the register. it's a u8, so keep it cute and keep it eight bits ⭐

that's the squad. go read them too, they're iconic 🌈

🧚 friendly reminder: ds1685_write is the plain, direct one. if you were looking for the sneaky indirect flavour, that's ds1685_indirect_write(9) — different girl, different vibe. don't mix them up bestie 😭
