STRUCT IWL_SAP_MSG_DW(9)

💅 struct iwl_sap_msg_dw(9) — Kernel API Manual, but make it make sense

okay so bestie, welcome to struct iwl_sap_msg_dw(9) — yes that's the page name, yes it's from the Kernel API Manual, and yes we're gonna get through it together 🫶

This is the little struct that "suits any DW long SAP message" — it's the generic DW-shaped envelope, no cap ✨

---

✨ NAME ✨

struct iwl_sap_msg_dw — suits any DW long SAP message 💌

---

🎀 SYNOPSIS 🎀

here's the whole vibe, literally verbatim, don't come for me:

struct iwl_sap_msg_dw {
    struct iwl_sap_hdr hdr;
    __le32 val;
 };

---

🌸 Members 🌸

okay so there's exactly two fields and honestly? iconic minimalism 🦋

• hdr — The SAP header 👑 it's the main character energy of this struct, every message carries one.
• val — The value of the DW 🌈 that's it, that's the payload.

ngl it's a two-field struct and it ate. periodt 💅
