💖 DESCRIPTION 💖

So basically this reads the target pathname of a symbolic link. that's the whole vibe. no cap. 🎀

• vp — the vnode of the symlink. the link itself, the icon, the moment. 👑
• uio — the location of the data to be read or written. where the tea gets poured. 🍓
• cred — the credentials of the caller. like, who even are you, bestie? 🙈
