create_multi_sg(9)

💅 create_multi_sg — the Kernel API Manual, bestie edition 🎀

okay so this is a page from the Kernel API Manual (that's the manual name, iykyk) and honestly? it's short but it ate. let's get into it ✨

---

✨ NAME ✨

create_multi_sg — makes a whole bunch of sg entries for you, each one carrying buflen worth of data, pulled straight out of the source sglist 🦋

---

🌸 SYNOPSIS 🌸

struct scatterlist * create_multi_sg (struct scatterlist *to_sg ,
                                      struct scatterlist *from_sg ,
                                      int buflen );

like, that's the whole vibe. one function call, three args, returns a pointer. periodt 💅

---

🎀 ARGUMENTS 🎀

• to_sg — the destination SG list, aka where the good stuff is going 💖
• from_sg — the source SG list, aka where the good stuff is coming from 🫶
• buflen — the data length, like how much data, in length units 🌸

---

👑 DESCRIPTION 👑

it returns the next free entry in the destination SG list. that's literally it, that's the whole description, no cap 😭

like — create_multi_sg does its thing, and what you get back is the pointer to the next slot that's still up for grabs in to_sg. main character energy honestly ✨
