✨ crypto_lskcipher_blocksize(9) ✨

okay bestie, buckle up — this is a page from the Kernel API Manual, and it's literally the cutest little getter you ever did see 💅

---

🎀 NAME 🎀

crypto_lskcipher_blocksize — obtain block size of cipher

like, you ask the cipher "hey girl, how big are your blocks?" and she tells you 🫶

---

🌸 SYNOPSIS 🌸

unsigned int crypto_lskcipher_blocksize (struct crypto_lskcipher *tfm );

one function, one argument, returns an unsigned int. no cap, that's the whole vibe ✨

---

🦋 ARGUMENTS 🦋

• tfm — cipher handle 💖 this is your little passport to the cipher, the thing you got back when you allocated it. no handle, no blocksize, periodt.

---

💜 DESCRIPTION 💜

so here's the tea: this function returns the block size for the lskcipher that the cipher handle (tfm) is referencing. that's it, that's the whole thing 🌈

and like… why do you care? because the caller — that's you, bestie — may use that information to allocate appropriate memory for the data returned by the encryption or decryption operation. so if you're about to encrypt or decrypt something and you need to know how much room to carve out, this is your girl. main character energy honestly 👑

---

⭐ RETURN ⭐

block size of cipher 🔥 that's the return value, and yes it's exactly what it says on the tin 💀
