STRUCT SCIFIOCTL_REG(9)

💅 NAME 💅

okay so bestie, welcome to struct scifioctl_reg(9) from the Kernel API Manual ✨ — this is the struct that's literally the main character for the SCIF_REG IOCTL. that's it, that's the vibe 🎀

🦋 SYNOPSIS 🦋

here's the whole glow-up, copy it exactly, no cap:

struct scifioctl_reg {
    __u64 addr;
    __u64 len;
    __s64 offset;
    __s32 prot;
    __s32 flags;
    __s64 out_offset;
 };

🌸 Members 🌸

every field gets its moment, periodt 💅

• addr — the starting virtual address, like where the whole thing begins 🗺️
• len — length of range, aka how much of it we're talking about 📏
• offset — offset of window, the little shift situation ✨
• prot — read/write protection, so you know what's allowed 🔐
• flags — flags. that's... the flags. they're flags, bestie 🚩
• out_offset — the offset that gets returned to you 🫶
