STRUCT BINFMT_MISC_FLAG(9)

struct binfmt_misc_flag(9) 🦋

okay bestie, this is from the Kernel API Manual, and it’s giving “tiny struct, main character energy” fr fr. No cap.

✨ NAME ✨

struct binfmt_misc_flag — a flag character of the register string. That’s the whole vibe 🎀

🌸 SYNOPSIS 🌸

Here’s the exact shape, bestie — keep the spacing cute and correct:

       struct binfmt_misc_flag {
           char c;
           unsigned long   flag;
           unsigned long   implies;
           const char      *desc;
        };

🎀 Members 🎀

• c — the character userspace writes and reads back. Both directions, icon behavior 💅
• flag — the entry flag it sets.
• implies — entry flags it turns on in addition. Sneaky little bonus flags, lowkey.
• desc — what it does, for the registration debug output. Your lil explanatory bestie 🫶
