ppc440spe_ad...xor_inc_addr(9)

💅 ppc440spe_ad...xor_inc_addr 💅

okay so this is a page from the Kernel API Manual, bestie, and it's about a function with a name so long it got its own abbreviation: ppc440spe_ad...xor_inc_addr(9). She's a kernel function, she's in section 9, and honestly? She's giving "I exist and that's enough." 🎀

✨ NAME ✨

ppc440spe_adma_dma2rxor_inc_addr — and no, the manpage does not elaborate. That's the whole name section. Iconic, honestly. It said what it said and dipped. 💅

---

🌸 SYNOPSIS 🌸

void ppc440spe_adma_dma2rxor_inc_addr (struct ppc440spe_adma_desc_slot
*desc , struct ppc440spe_rxor *cursor , int index , int src_cnt );

so she takes four things and returns void — nothing back, no receipts, just vibes and side effects. 🦋

---

💖 ARGUMENTS 💖

okay bestie, brace yourself, because the documentation here is lowkey on strike:

• desc — -- undescribed -- 😭
• cursor — -- undescribed -- 😭
• index — -- undescribed -- 😭
• src_cnt — -- undescribed -- 😭

that's it. that's the whole arguments section. all four of them are marked undescribed, which is the manual-page equivalent of a group chat reply that's just "lol". 🙈

ngl this is a whole mood. the page is telling you these parameters exist and that's all it's willing to commit to — no cap, do not go inventing meanings for them, because the original for real doesn't say. if you need the details, you're gonna have to go read the source, bestie.
