media_graph_walk_start(9)

💅 media_graph_walk_start — start walking the media graph at a given entity ✨

okay bestie, this page is from the Kernel API Manual, and it's literally media_graph_walk_start(9). Buckle up, it's giving “legacy graph-walk realness” with a big deprecation glow-up. 🫶

🌸 NAME 🌸

media_graph_walk_start — Start walking the media graph at a given entity.

✨ SYNOPSIS ✨

void media_graph_walk_start (struct media_graph *graph , struct media_entity *entity );

🎀 ARGUMENTS 🎀

• graph — the media graph structure that will be used to walk the graph. it's the map you're strolling through 🗺️
• entity — the starting entity. your main character starting point 👑

🦋 DESCRIPTION 🦋

🚨 deprecated alert: “This function is deprecated, use media_pipeline_for_each_pad instead.” no cap, take the hint 💀

Before using this function, media_graph_walk_init must be used to allocate resources used for walking the graph. Think of it as packing snacks before the walk. 🍓

This function initializes the graph traversal structure to walk the entities graph starting at the given entity. The traversal structure must not be modified by the caller during graph traversal — like, do not touch it while it's walking, bestie. 🙈

After the graph walk, the resources must be released using media_graph_walk_cleanup. cleanup era, we love to see it ✨
