drm_file_alloc(9)

🎀 drm_file_alloc(9) 🎀

okay bestie, welcome to drm_file_alloc(9) — straight out of the Kernel API Manual, and honestly? it's giving "small function, big responsibility" ✨

---

💖 NAME 💖

drm_file_alloc — allocate file context 🗂️✨

---

🌸 SYNOPSIS 🌸

struct drm_file * drm_file_alloc (struct drm_minor *minor );

like, that's it. that's the whole vibe. one argument, one pointer back 🫶

---

🦋 ARGUMENTS 🦋

• minor — the minor to allocate on 💅 this is the DRM minor you're hitching your brand-new file context to, no cap

---

👑 DESCRIPTION 👑

so what does it actually do? it allocates a shiny new DRM file context for you 🎀

and here's the cute part: the new context is not linked into any context — it's a free agent, main character energy, and the caller can use it freely however they want 💫

🚨 but listen, this is important: the context keeps a pointer to minor, so it must be freed before minor is. like. non-negotiable. don't let the context outlive its minor or it's gonna be a whole thing 💀

---

⭐ RETURN ⭐

• Pointer to the newly allocated context 🥳
• ERR_PTR on failure 😭 (yes, the error-pointer situation, you know the one)
