mraid_mm_get_adapter(9)

💅 mraid_mm_get_adapter — kernel API manual, section 9 🎀

okay bestie, settle in, because we're doing kernel API hours and this one is lowkey iconic: mraid_mm_get_adapter(9). yeah. section 9. we're in that part of the manual, the driver-internals part. grab a strawberry drink 🍓 and let's go.

---

✨ NAME ✨

mraid_mm_get_adapter — returns the corresponding adapters for the mimd packet 🫶

---

🌸 SYNOPSIS 🌸

mraid_mmadp_t * mraid_mm_get_adapter (mimd_t __user *umimd , int *rval );

like, look at her. one function, two args, a pointer coming out. main character energy fr fr 👑

---

🦋 ARGUMENTS 🦋

• umimd — the user space mimd_t ioctl packet 💌 this is the thing coming at you from userspace, so yes, the __user is doing a lot of heavy lifting there.
• rval — the returned success/error status 🌈 out-param behaviour, she's writing back to you, that's the whole vibe.

---

💖 DESCRIPTION 💖

so the function's return value? it's a pointer to the located adapter. that's the tea ☕ literally the entire description. you hand it the packet, it hands you back a pointer to the adapter it found. not me being obsessed with a one-line description 😭 it's giving confident. it's giving "I said what I said."

lowkey important: the rval out-param is where the success/error status lands, so don't go ignoring her bestie 💅
