💅 smack_watch_key — a whole manual page, bestie ✨

okay so real talk, this is smack_watch_key(9) from the Kernel API Manual and it's genuinely such a mood. it's a little function that decides whether you're allowed to watch a key for notifications, and i'm obsessed with how simple it is. let's get into it 🫶

🌸 NAME 🌸

smack_watch_key — the Smack security check for watching a key for notifications. that's it, that's the whole vibe. main character energy for real.

🎀 SYNOPSIS 🎀

int smack_watch_key (struct key *key );

she's short, she's sweet, she takes exactly one pointer. periodt. 💖

🦋 ARGUMENTS 🦋

  • key — the key to be watched 👀 like, the actual key object we're trying to keep an eye on. that's the one and only argument, no cap.

✨ DESCRIPTION ✨

okay so here's the tea, bestie: smack_watch_key returns 0 if the watch's cred has permission to read from the key object, and returns an error otherwise. that's literally it. no extra lore, no secret side quests — just a clean yes-or-no permission check. slay. 💅

ngl this one's a short one. lowkey iconic of her to not overexplain. we love a concise queen.
