vfs_fstat(9)

💅 vfs_fstat 💅

okay bestie, welcome to the Kernel API Manual ✨ — this little cutie lives in section 9 and honestly she's giving "small but mighty." 🎀

---

🌸 NAME 🌸

vfs_fstat — literally just Get the basic attributes by file descriptor 🦋

---

✨ SYNOPSIS ✨

int vfs_fstat (int fd , struct kstat *stat );

yes, that spacing is real, we don't fix what isn't broken 💅

---

🫶 ARGUMENTS 🫶

• fd — the file descriptor referring to the file of interest 👀 like, which file are we talking about here, bestie
• stat — the result structure to fill in. she comes empty, she leaves full of lore 🍓

---

💖 DESCRIPTION 💖

so this function is a wrapper around vfs_getattr — same energy, slightly different outfit 💅 the main difference is that it uses a file descriptor to determine the file location. that's it, that's the whole glow-up ✨

0 will be returned on success 🎉 and a -ve error code if unsuccessful 😭 (yes, negative, we love a dramatic exit).

ngl, if you see a negative number come back, something did NOT slay. check your fd, check your vibes 💀
