STRUCT SCIFIOCTL_NODE_IDS(9)

💅 struct scifioctl_node_ids(9)

okay so bestie, welcome to the Kernel API Manual ✨ — this is the page for struct scifioctl_node_ids, and it's literally the struct that the SCIF_GET_NODEIDS IOCTL uses. that's it, that's the whole vibe. small struct, big main character energy 👑

---

🌸 NAME 🌸

struct scifioctl_node_ids — used for SCIF_GET_NODEIDS IOCTL 🫶

---

✨ SYNOPSIS ✨

here's the whole thing, no cap, copied exactly:

struct scifioctl_node_ids {
    __u64 nodes;
    __u64 self;
    __s32 len;
 };

like… three fields and a dream 😭 she's compact, she's iconic, she's a struct.

---

🎀 Members 🎀

• nodes — pointer to an array of node_ids 🔥 that's right, it's a pointer to the array, not the array itself, don't get it twisted.
• self — the ID of the current node 🌟 (yes, the node you're on right now — she's self-referential like that, very meta 💅).
• len — length of the array 📏 okay so this is how many entries live in that array. the __s32 is signed, that's just what the struct says, don't come for me.

bestie that's genuinely all of it 💖 nothing hidden, nothing extra — the struct, the three members, and the friend group. go read the friends too, iykyk 🌈
