ecryptfs_fin...emon_by_euid(9)

✨ NAME ✨

ecryptfs_find_daemon_by_euid — (the description after the dash is literally empty in the original, so that’s the whole vibe 🫶)

Okay so bestie, this is the ecryptfs_fin...emon_by_euid(9) page from the Kernel API Manual — yes, the title is truncated exactly like that in the header, and no, we are not fixing it 💅.

---

🌸 SYNOPSIS 🌸

int ecryptfs_find_daemon_by_euid (struct ecryptfs_daemon **daemon );

---

🎀 ARGUMENTS 🎀

• daemon — if the return value is zero, this points to the desired daemon pointer. That’s the whole argument list, periodt ✨

---

🦋 DESCRIPTION 🦋

Okay so before you do literally anything: this must be called with ecryptfs_daemon_hash_mux held 🔒 no cap, that’s a requirement.

Then it searches the hash list for the current effective user id.

Returns zero if the user id exists in the list; non-zero otherwise. It’s giving lookup-with-a-vibe-check: zero means the user id is in there, non-zero means it isn’t 💅
