STRUCT BRCMF_VNDR_DCMD_HDR(9)

💖 struct brcmf_vndr_dcmd_hdr(9) 💖

okay bestie, so this is a page from the Kernel API Manual, section 9 — yes we're reading kernel docs for fun now, that's just who we are 💅 and honestly? this one's a little cutie.

✨ NAME ✨

struct brcmf_vndr_dcmd_hdr — the message header for the cfg80211 vendor command dcmd support 🫶 like, it's literally the little name tag every vendor dcmd message wears so everybody knows what it is.

🌸 SYNOPSIS 🌸

struct brcmf_vndr_dcmd_hdr {
    uint cmd;
    int len;
    uint offset;
    uint set;
    uint magic;
 };

five fields. that's it. she's compact, she's iconic, she's doing her job 👑

🎀 Members 🎀

• cmd — the common dongle cmd definition 💫 iykyk, this is the "which command are we even doing" field.
• len — length of expecting return buffer 📏 notice it's an int, not a uint, ok? we're being precise. it's the length of the buffer you're expecting to get back.
• offset — offset of data buffer 🧭 like where in the buffer the data actually starts.
• set — get or set request (optional) 🔁 yeah it's got that optional energy — are we getting or are we setting, that's the whole vibe check.
• magic — magic number for verification ⭐ very main character of her. it's there so you can verify stuff, no cap.

bestie pls don't sleep on the types — cmd, offset, set and magic are all uint, but len is a plain int. the original says it that way and so do I 🙈
