💅 memstick_init_req(9) 💅

okay so bestie, welcome to the Kernel API Manual — this one's about memstick_init_req, and no cap, it's a little cutie. It sets up the request fields you need for a short data transfer ✨

---

🌸 SYNOPSIS 🌸

void memstick_init_req (struct memstick_request *mrq , unsigned char tpc , const void *buf , size_t length );

like, that's the whole signature. she's compact, she's iconic 🎀

---

🦋 ARGUMENTS 🦋

• mrq — the request you're gonna use 🫶
• tpc — the memstick Transport Protocol Command, iykyk
• buf — the TPC argument buffer, where the data lives
• length — the TPC argument size, aka how much of it there is

---

💖 DESCRIPTION 💖

so the intended use of this function is transferring data items that are several bytes in size — and because it's only a few bytes, the move is literally just copying the value between the request structure and the user supplied buffer. that's it. that's the whole vibe check. no cap, she's simple and we're obsessed 💅
