STRUCT QAIC_MANAGE_TRANS_HDR(9)

💅 struct qaic_manage_trans_hdr(9) — Kernel API Manual 🎀

okay so bestie, buckle up — this is the header every single transaction in a manage message rolls with. it's giving "small but runs the whole group chat" energy, and honestly? iconic. this one lives in the kernel API manual, and we're gonna get you fluent, no cap. ✨

🌸 NAME 🌸

struct qaic_manage_trans_hdr — the header for a transaction in a manage message. yeah. it's the little name tag every transaction wears so everybody knows who's who at the party 🫶

---

⭐ SYNOPSIS ⭐

struct qaic_manage_trans_hdr {
    __u32 type;
    __u32 len;
 };

two __u32s. that's it. that's the whole vibe. lowkey elegant, highkey essential 💖

---

🦋 Members 🦋

so there's literally only two, and they both go in (as in input, bestie — they're things you tell the kernel, not things it tells you):

• type — In. this is the "who dis" field. it identifies the transaction. peek at the QAIC_TRANS_* defines to see all the flavors you can pick from. choose wisely, it's main character energy 👑
• len — In. the length of this transaction, including this header itself. yes, including. don't forget to count the header or the whole message gets its vibe check failed 😭

bestie reminder: type and len are both In fields. you're the one supplying them. the kernel's just sitting there like "okay girl, go off" 💅

that's the whole page, and honestly? slayed. this beauty ships out of ./include/uapi/drm, dated October 2026, and its title is still the full struct qaic_...ge_trans_hdr(9) glow-up. mwah 💋 periodt. 🍓✨🧚
