UNION KS8851_TX_HDR(9)

💖 union ks8851_tx_hdr(9) 💖

okay so bestie, welcome to the Kernel API Manual — today's main character is union ks8851_tx_hdr, and it's literally the tx header data. that's it, that's the vibe. 🎀

---

✨ NAME ✨

union ks8851_tx_hdr — tx header data

like... it's a union, it's a tx header, it holds data. iconic behavior honestly. 💅

---

🌸 SYNOPSIS 🌸

union ks8851_tx_hdr {
    u8 txb[6];
    __le16 txw[3];
 };

look at her. six bytes, three little-endian 16-bit words, same memory, two outfits. dual representation realness. ✨

---

🦋 Members 🦋

• txb — the header as bytes, bestie. raw, unfiltered, one byte at a time. 🍓
• txw — the header as 16bit, little-endian words. three of them. exactly three. no cap. 💜

---

🌈 Description 🌈

so the whole point, and i need you to hear me on this: it's a dual representation of the tx header data. that's the entire thing. she's living two lives and both of them are valid. 😭

it lets you get at the individual bytes — hello txb — and it also lets you do 16bit accesses with 16bit alignment — hello txw, look at you thriving with your alignment. 🫶

two views, one chunk of memory. main character energy fr fr. 👑
