get_old_itimerspec32(9)

💅 get_old_itimerspec32(9) — from the Kernel API Manual, bestie

okay so picture this: it's a kernel function, it lives in the Kernel API Manual, and its whole personality is taking your userspace timerspec and putting it where the kernel can see it. no cap, that's the gig. 🎀

---

✨ NAME ✨

get_old_itimerspec32 — literally the function that gets the user's &struct old_itimerspec32 into kernel space. that's it. that's the whole vibe. 💖

---

🌸 SYNOPSIS 🌸

int get_old_itimerspec32 (struct itimerspec64 *its , const struct
old_itimerspec32 __user *uits );

---

🦋 ARGUMENTS 🦋

• its — the destination struct itimerspec64. this is where the good stuff lands, main character energy fr. ✨
• uits — the user's struct old_itimerspec32. yes it's __user, yes it's coming from userspace, be normal about it. 🙈

---

⭐ RETURN ⭐

0 on success, or a negative errno on error. slay when it's 0, 😭 when it's negative. that's the whole return situation, iykyk.
