STRUCT SCIFIOCTL_UNREG(9)

💖 NAME 💖

hey bestie, welcome to the struct scifioctl_unreg(9) page from the Kernel API Manual. This is lowkey a tiny kernel struct, but she has a job: she's used for the SCIF_UNREG IOCTL.

• struct scifioctl_unreg — used for the SCIF_UNREG IOCTL.

✨ SYNOPSIS ✨

okay so here's the exact struct, no cap — this is the whole thing:

struct scifioctl_unreg {
    __s64 offset;
    __u64 len;
};

the way that this is literally just two fields is sending me 🫶

💅 Members 💅

the member breakdown, because we respect the details:

• offset — start of range to unregister.
• len — length of range to unregister.

that's the entire struct. periodt. 💅
