media_graph_walk_next(9)

💅 media_graph_walk_next(9) — the manual page, bestie edition

okay so this is a page from the Kernel API Manual (yes, the kernel has lore too, we love that for it) and today we're talking about media_graph_walk_next ✨

---

🌸 NAME 🌸

media_graph_walk_next — get the next entity in the graph, fr fr

---

🎀 SYNOPSIS 🎀

struct media_entity * media_graph_walk_next (struct media_graph *graph
);

like, that's the whole call. iconic. short. slay.

---

🦋 ARGUMENTS 🦋

• graph — the media graph structure 💫 this is the graph you're walking through, bestie.

---

✨ DESCRIPTION ✨

🚨 important heads-up first: this function is deprecated. do not use it. use media_pipeline_for_each_pad instead, periodt. 💀

okay so what does it do? It performs a depth-first traversal of the given media entities graph. like it goes deep first, then comes back around — very main character energy. 🌈

The graph structure must have been previously initialized with a call to media_graph_walk_start — no init, no walk, that's the vibe check. 🫶

---

💖 RETURN 💖

It returns the next entity in the graph, or NULL if the whole graph has been traversed. so when you get NULL, that's your cue that the walk is over — no cap. 🌸
