mcb_request_mem(9)

💅 mcb_request_mem(9) — like, the Kernel API Manual, but make it make sense 🎀

okay bestie, buckle up — this one lives in the mcb_request_mem(9) chapter of the Kernel API Manual and it's honestly such a vibe. it's giving "one function, one job, no drama." let's get into it ✨

---

🌸 NAME 🌸

mcb_request_mem — Request memory 🫶

like, that's it. that's the whole name. requesting memory. iconic behavior, no notes.

---

✨ SYNOPSIS ✨

struct resource * mcb_request_mem (struct mcb_device *dev , const char
*name );

yep, that's the whole signature, character for character, don't @ me 💅

---

🦋 ARGUMENTS 🦋

so there's exactly two things you gotta hand over, and here's the tea:

• dev — The mcb_device the memory is for 👑 this is the main character of the whole call, the device that's getting the memory.
• name — The name for the memory reference. 🎀 that's the label you're slapping on this memory reference.

---

💖 DESCRIPTION 💖

okay so here's what's actually happening: you're requesting memory for a mcb_device. that's the whole plot. 🍓

and here's the cute little plot twist — if name is NULL the driver name will be used. so like, no name? no problem, the driver name slides in and takes over. lowkey thoughtful of it, honestly 🙈
