st_i2c_xfer_msg(9)

📦 version 7.3.1, in nixpkgs unstable

💅 st_i2c_xfer_msg(9) — like, the whole kernel API manual moment 🎀

okay bestie, welcome to the Kernel API Manual entry for st_i2c_xfer_msg — yes it's a section 9 page, yes it's driver-internals core, and yes we're gonna get through it together 💖

✨ NAME ✨

st_i2c_xfer_msg — Transfer a single I2C message 🦋

like, one message. singular. that's the whole vibe. no cap.

🌸 SYNOPSIS 🌸

int st_i2c_xfer_msg (struct st_i2c_dev *i2c_dev , struct i2c_msg *msg ,
bool is_first , bool is_last );

she takes four things and returns an int, periodt 💅

🫶 ARGUMENTS 🫶

  • i2c_dev — the controller's private data ✨ like this is her little stash of controller-specific info, ok?
  • msg — the I2C message to transfer 📨 the actual thing being sent out
  • is_first — bool, marks this as the first message of the sequence 👑 main character energy, opening act
  • is_last — bool, marks this as the last message of the sequence 🎬 closing scene, the finale

like the way that is_first and is_last are both bools and both tell you where you are in the sequence?? lowkey iconic. iykyk.

🔥 SEE ALSO 🔥

okay so this is the part where the manpage flexes its whole friend group 😭 the kernel file ./drivers/i2c/busses/i2c-st.c and, like, every sibling function:

the whole squad fr fr 🧚💜 go read them, they're literally all right there

ngl there's no OPTIONS section, no RETURN VALUE section, no ERRORS, no BUGS, no environment variables, no signals, no exit statuses — this page is short and she knows it. don't go looking for stuff that isn't here bestie, i'm not gonna invent it 🙈

kisses and bye-bye from ./drivers/i2c/busses, dated October 2026 — that's the source and the version and the date all in one cute little sign-off 🌈⭐ slay, go transfer exactly one (1) I2C message 💀💖
