💫 qmi_decode_message 💫

okay so bestie, welcome to the qmi_decode_message(9) page — yes that's the Linux Kernel API Manual, and yes we're about to make QMI decoding make sense together, no cap 🫶

✨ NAME ✨

qmi_decode_message — decode a QMI encoded message into a C structure 🎀

Like, that's literally the whole vibe: encoded bytes go in, a nice lil' C struct comes out 💅

🌸 SYNOPSIS 🌸

int qmi_decode_message (const void *buf , size_t len , const struct qmi_elem_info *ei , void *c_struct );

🦋 ARGUMENTS 🦋

  • buf — the buffer holding the encoded message 💌 like, this is the raw stuff you're feeding in.
  • len — how much data is actually in buf. not more, not less, be honest about it 🙈
  • ei — the QMI message descriptor ✨ it's the lil' map that tells the decoder what it's looking at.
  • c_struct — a reference to the structure you wanna decode into 🫶 this is where the good stuff lands.

👑 RETURN 👑

On success you get the number of bytes of decoded information 🎉 and if something goes wrong? negative errno on error 😭 (yes, that's the standard kernel heartbreak).
