inode_set_ctime(9)

💅 inode_set_ctime — a Kernel API Manual moment (that's the manual name bestie, section 9, we're in kernel-land)

okay so picture this: you're deep in the kernel, you've got an inode, and its ctime is just... not it. you need to fix it. that's the whole vibe of this page. it's inode_set_ctime, and it does exactly one (1) thing and does it flawlessly. main character energy fr fr 🎀

---

✨ SYNOPSIS ✨

struct timespec64 inode_set_ctime (struct inode *inode , time64_t sec ,
long nsec );

so like, it hands you back a struct timespec64, cute of it. takes three things, gives you one back. balanced. iconic. 💖

---

🌸 ARGUMENTS 🌸

• inode — the inode you're setting the ctime on, obviously. the target. the chosen one. 🫶
• sec — the tv_sec value you wanna set. the big seconds. the whole-number part of the story.
• nsec — the tv_nsec value you wanna set. the lil nanoseconds, the fine print, the sparkle on top ✨

---

💫 DESCRIPTION 💫

okay so the actual deal: it sets the ctime in inode to { sec, nsec }. that's it. that's the function. no hidden lore, no side quests, no plot twists. you give it an inode and a time, it puts the time in the inode. slay.

ngl the simplicity is the point here — it's giving "i do one job and i do it well" and honestly? we respect it. 👑

lowkey a reminder that sec and nsec are the two halves of one timestamp — tv_sec and tv_nsec — and they go in together as { sec, nsec }. don't split them up bestie, they're a package deal 💀
