aead_request_alloc(9)

💖 aead_request_alloc(9) 💖

okay so bestie, welcome to the aead_request_alloc page — it's from the Kernel API Manual and it's literally the glow-up moment where your request data structure gets born ✨

---

🌸 NAME 🌸

aead_request_alloc — allocate request data structure (yes that's the whole job, and she does it flawlessly 💅)

---

🦋 SYNOPSIS 🦋

struct aead_request * aead_request_alloc (struct crypto_aead *tfm ,
gfp_t gfp );

---

🎀 ARGUMENTS 🎀

• tfm — the cipher handle that gets registered with the request 🫶 like, she's the plus-one you're bringing to the party.
• gfp — the memory allocation flag that's handed off to kmalloc by the API call. it's giving "pass the note along" energy ngl.

---

✨ DESCRIPTION ✨

So here's the vibe: this call allocates the request data structure that you must use with the AEAD encrypt and decrypt API calls. no substitutions, bestie, this is the one 👑

And during the allocation, the aead handle you provided gets registered right into the request data structure. main character registration moment fr fr 🌟

---

🌈 RETURN 🌈

• allocated request handle in case of success 💖
• or NULL if out of memory 😭 (the tragedy, the drama, the -ENOMEM of it all)
