STRUCT SCIFIOCTL_FENCE_SIGNAL(9)

💅 struct scifioctl_fence_signal — Kernel API Manual, section 9 🎀

okay bestie so this is a page from the Kernel API Manual, section 9 (the kernel interfaces girlies, iykyk), and it's all about struct scifioctl_fence_signal. literally the whole personality of this struct is "used for SCIF_FENCE_SIGNAL IOCTL". that's it, that's the vibe. ✨

---

🌸 NAME 🌸

struct scifioctl_fence_signal — used for SCIF_FENCE_SIGNAL IOCTL. no cap, that's the entire job description. 💅

---

🦋 SYNOPSIS 🦋

struct scifioctl_fence_signal {
    __s64 loff;
    __u64 lval;
    __s64 roff;
    __u64 rval;
    __s32 flags;
 };

she's giving five fields, two sides (local + remote), and one little flags field doing her own thing. iconic honestly. 👑

---

🎀 Members 🎀

• loff — local offset. the local side's address, bestie. 📍
• lval — value to write to loffset. this is the thing that gets written there, fr fr. ✍️
• roff — remote offset. same energy as loff but like… over there. 🌐
• rval — value to write to roffset. the remote-side value, periodt. 💫
• flags — flags. yes queen, it's just flags. that's the whole description and we respect it. 🚩

squad goals, honestly. 🌈✨

and that's the page!! 💖 this little cutie lives in ./include/uapi/linux and the header says October 2026 on it, so mark ur calendar bestie — that's the date stamped on this icon of a manpage. go forth and fence ur signals responsibly 🧚‍♀️⭐
