📦 version 7.3.1, in nixpkgs unstable

💅 drm_dp_dual_mode_write(9) — like, the Kernel API Manual page you actually wanna read 🎀

okay so bestie, welcome to drm_dp_dual_mode_write, straight out of the Kernel API Manual ✨ this one's short and sweet and honestly? kinda iconic. let's get into it 🫶

🌸 NAME 🌸

drm_dp_dual_mode_write — the function that writes to the DP dual mode adaptor register(s). that's it, that's the whole vibe 💖

✨ SYNOPSIS ✨

ssize_t drm_dp_dual_mode_write (struct i2c_adapter *adapter , u8 offset
, const void *buffer , size_t size );

look at her. ssize_t return type, four params, zero notes. main character energy fr 🔥

🦋 ARGUMENTS 🦋

  • adapter — the I2C adapter for the DDC bus. yes, this is where the whole conversation happens 💅
  • offset — the register offset, a lil u8 telling everyone where to start writing 🎀
  • buffer — the buffer holding your write data, const void * so nobody's out here mutating your stuff 🙈
  • size — size of the buffer, size_t girlie, because bytes are bytes ✨

💜 DESCRIPTION 💜

so the actual job: it writes size bytes into the DP dual mode adaptor registers, starting at offset. that's literally it. no lore, no side quests — just a clean write of size bytes beginning at offset 🔥

ngl, the way this function just gets in, does its thing, and leaves? that's the energy we should all be bringing 🌈

⭐ RETURN ⭐

  • returns 0 on success 👑
  • returns a negative error code on failure 😭 (yes, negative. check it, bestie.)
