ecryptfs_validate_marker(9)

✨ ecryptfs_validate_marker(9) ✨

okay so bestie, welcome to the Kernel API Manual, section 9 — yes we're in the big-kid kernel docs now, and this one's a tiny little icon but she's important 💅

---

💖 NAME 💖

ecryptfs_validate_marker — the girl who checks for the ecryptfs marker 🎀

---

🌸 SYNOPSIS 🌸

int ecryptfs_validate_marker (char *data );

that's it. that's the whole vibe. one function, one char *, no cap 🫶

---

🦋 ARGUMENTS 🦋

• data — the data block in which to check 👀 like, hand her the block and she'll look inside it for the marker, that's literally her whole job bestie

---

⭐ DESCRIPTION ⭐

so here's the tea: she returns zero if the marker is found — zero! the good number! the slay number! ✨

and if it's not found? you get -EINVAL 😭 that's it, that's the whole story. found = 0, not found = -EINVAL, no in-between, no dramatic monologue, she's very straightforward about it.

ngl this is the entire function description, so don't go looking for extra lore — the manpage keeps it short and honestly? iconic behaviour. minimal, focused, main character energy 💀

---

💜 SEE ALSO 💜

okay this is the part where she tags all her friends and honestly the list is long, so buckle up buttercup 🌈
