📦 version 7.3.1, in nixpkgs unstable

💅 xbc_node_get_child — the kernel API manual, bestie edition

okay so real quick, the manual page is literally called xbc_node_get_child(9) and it lives in the Kernel API Manual, and yes we're getting into it 🎀

🌸 NAME 🌸

xbc_node_get_child — get the child XBC node. that's it. that's the whole name. iconic brevity 💖

✨ SYNOPSIS ✨

struct xbc_node * xbc_node_get_child (struct xbc_node *node );

copy it exactly like that, spacing and all — no cap, the compiler is not forgiving 🙈

🦋 ARGUMENTS 🦋

  • node — an XBC node. that's your starting point, your main character, the node you're asking about 🫶

🔥 DESCRIPTION 🔥

okay so here's the tea: xbc_node_get_child returns the first child node of node. that's the whole job. it's giving "eldest sibling" energy 👑

and if the node has no child? it returns NULL. no child, no node, no drama, just NULL 💀 so like, always check before you dereference, bestie, that's the vibe check 🧚

🌈 SEE ALSO 🌈

all the sibling functions you should also know, because the kernel file ./lib/bootconfig.c is a whole friend group and you can't just know one of them 💜

fun fact from the original page: that whole list is coming at you from the kernel file ./lib/bootconfig.c. go read it, iykyk 📖

🍓 sign-off 🍓
