cb710_sg_dwi...e_next_block(9)

💖 NAME 💖

cb710_sg_dwiter_write_next_block — bestie, this is the one that writes the next 32-bit word into the sg buffer ✨

So like, quick vibe check: this page lives in the Kernel API Manual (that's the manual name, iykyk), and it's all about pushing one lil 32-bit word out into an sg buffer. Slay.

---

🌸 SYNOPSIS 🌸

void cb710_sg_dwiter_write_next_block (struct sg_mapping_iter *miter ,
uint32_t data );

---

🎀 ARGUMENTS 🎀

• miter — the sg mapping iterator that's doing the writing, no cap 💅
• data — the actual data you're writing to the sg buffer, periodt

---

🦋 DESCRIPTION 🦋

Okay so here's the tea ☕: this function writes a 32-bit word starting at the byte that miter is pointing at, and it handles any alignment issues along the way — she's flexible like that 🧚

Any bytes that would end up written past the end of the buffer? Yeah those get silently discarded. Not a crash, not an error, just... gone. Poof. 🙈

And then miter gets advanced by 4 bytes, or to the end of the buffer — whichever one is closer. Main character energy honestly 👑

---

⭐ CONTEXT ⭐

Same requirements as in sg_miter_next. That's it, that's the whole vibe check 🫶

---

🔥 SEE ALSO 🔥

• Kernel file ./drivers/misc/cb710/sgbuf2.c
• cb710_sg_dwiter_read_next_block(9) — the read girlie, her sister function 💜

---

Heads up bestie: that "silently discarded" bit is real — there's no error return here, so if you're writing past the end of the buffer you literally will not be told 😭 Plan accordingly fr fr.

That's the whole page!! 🎀 Written for the ./drivers/misc/cb710 source, dated October 2026 — go off, you understand Unix now, I'm so proud of you 💖✨
