💅 af_alg_count_tsgl(9)

okay so bestie, welcome to the Kernel API Manual — we're literally in af_alg_count_tsgl(9) territory and it's giving "tiny function, big responsibility" energy. This one's whole thing? Counting TX SG entries. that's it. that's the vibe. ✨

---

🌸 NAME 🌸

af_alg_count_tsgl — Count number of TX SG entries

like, it counts SG entries. TX ones. for real. 🎀

---

🦋 SYNOPSIS 🦋

unsigned int af_alg_count_tsgl (struct sock *sk , size_t bytes );

that's literally the whole signature, no cap 💅

---

✨ ARGUMENTS ✨

• sk — the socket of the connection to user space. bestie's channel to the outside world 🫶
• bytes — count the number of SG entries holding the given number of bytes. you tell it how many bytes, it tells you how many entries are holding them 👑

---

🔥 DESCRIPTION 🔥

the counting starts from the beginning of the SGL and runs up to bytes. that's it. that's the whole journey: from the top of the scatterlist, all the way to your bytes cutoff. slay 💀

---

⭐ RETURN ⭐

number of TX SG entries found, given the constraints. a plain unsigned int, no drama, no error codes, just a count 😭👑
