akcipher_re...set_callback(9)

💖 akcipher_re...set_callback(9) 💖

okay so this is from the Kernel API Manual, and the page is literally called akcipher_re...set_callback (yes the name is truncated with dots, that's just how it is bestie, don't come for it 💅). Buckle up, we're setting callbacks on async akcipher requests and it's gonna be iconic.

✨ NAME ✨

akcipher_request_set_callback — sets an asynchronous callback. that's it. that's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

void akcipher_request_set_callback (struct akcipher_request *req , u32
flgs , crypto_completion_t cmpl , void *data );

like, look at her. four params, returns void, zero drama. 🦋

---

🧚 ARGUMENTS 🧚

• req — the request that the callback will be set for. this is the main character of the operation, the one we're attaching the callback to. 👑
• flgs — flags, and they specify for instance if the operation may backlog. yes it's spelled flgs, no we're not fixing it, it's canon. 💀
• cmpl — the callback which will be called. the whole point of the function honestly, the cmpl is the moment. 🔥
• data — private data used by the caller. your little stash, your personal lore, passed through for you. 🙈

---

💜 DESCRIPTION 💜

so basically: the callback will be called when an asynchronous operation on a given request is finished. that's the tea. you hand over your cmpl and your data, and when the async op wraps up on that req, your callback gets the glow-up and runs. no cap, that's the entire behavior described here. ⭐
