OF_CHILD(9)

🌸 NAME 🌸

okay so bestie, this is the OF_CHILD(9) page from the Kernel Developer's Manual 💖 and it's all about OF_child, OF_parent, and OF_peer — navigate device tree energy, fr fr. no cap.

✨ SYNOPSIS ✨

first, include these headers, periodt:

#include <dev/ofw/ofw_bus.h>
#include <dev/ofw/ofw_bus_subr.h>

then the function signatures, exactly like this:

phandle_t
OF_child(phandle_t node);

phandle_t
OF_parent(phandle_t node);

phandle_t
OF_peer(phandle_t node);

💅 DESCRIPTION 💅

• OF_child() — returns the phandle value of the first child of node. zero is returned if there are no child nodes. slay.
• OF_parent() — returns the phandle for the parent of node. zero is returned if node is the root node. obsessed.
• OF_peer() — returns the phandle value of the next sibling of node. zero is returned if there is no sibling node. iconic.

🌈 EXAMPLES 🌈

example time, bestie — here's the loop exactly as the page gives it:

       phandle_t node, child;
        ...
       for (child = OF_child(node); child != 0; child = OF_peer(child) {
               ...
       }
