of_graph_get_next_endpoint(9)

💅 of_graph_get_next_endpoint(9) — get next endpoint node 🎀

Okay so bestie, listen up, this is from the Kernel API Manual and it's literally about walking the device tree graph, one endpoint at a time. It's giving "traverse the graph, queen" energy and I'm obsessed. ✨

🌸 SYNOPSIS 🌸

struct device_node * of_graph_get_next_endpoint (const struct device_node *parent , struct device_node *prev );

🦋 ARGUMENTS 🦋

• parent — pointer to the parent device node 💖 (this is the node you're poking around in, iykyk)
• prev — previous endpoint node, or NULL to get the first one 🌟 (pass NULL when you're starting fresh, no cap)

👑 RETURN 👑

An 'endpoint' node pointer with refcount incremented. And the way that it also decrements the refcount of the passed prev node — periodt, that's the whole deal. 💅

Not me reminding you to handle your refcounts properly, bestie — this function does the increment/decrement dance for you, but you still gotta be responsible with the pointer it hands back. 🫶
