proc_douintvec(9)

💅 proc_douintvec(9) — a Kernel API Manual moment ✨

okay so bestie, welcome to the proc_douintvec(9) page, straight out of the Kernel API Manual 💖 this is the one that reads and writes a whole vector of unsigned integers and honestly? she ate. no cap.

---

✨ NAME ✨

proc_douintvec — read a vector of unsigned integers 🎀 literally what it says on the tin, and she does it flawlessly.

---

🌸 SYNOPSIS 🌸

int proc_douintvec (const struct ctl_table *table , int dir , void
*buffer , size_t *lenp , loff_t *ppos );

that's the whole signature, bestie — copy it exactly, don't be out here retyping the commas like a menace 🙈

---

🦋 ARGUMENTS 🦋

• table — the sysctl table, aka the main character of this whole situation 👑
• dir — TRUE if this is a write to the sysctl file. like, are we writing? are we reading? this lil flag knows 🫶
• buffer — the user buffer, where the actual data hangs out ✨
• lenp — the size of the user buffer, so nobody oversteps 💀
• ppos — file position. where we're at, no cap 📍

---

💜 DESCRIPTION 💜

so here's the vibe: it reads/writes up to table->maxlen/sizeof(unsigned int) unsigned integer values from/to the user buffer, treated as an ASCII string 🌈

that's it, that's the whole plot. the number of values it can handle is that maxlen-divided-by-sizeof-expression, and the user buffer gets treated as an ASCII string the entire time. iykyk 💅

---

⭐ RETURN ⭐

0 on success ✨ that's the good ending, the slay ending, the one we want 🎀
