🌸 parse_int_array_user(9) 🌸

okay so bestie, welcome to the Kernel API Manual — this one's a little function from the kernel that literally just splits a string into a whole sequence of integers. it's giving "glow-up for your string parsing era" 💅

---

✨ NAME ✨

parse_int_array_user — split a string into a sequence of integers 💖

---

🎀 SYNOPSIS 🎀

int parse_int_array_user (const char __user *from , size_t count , int **array );

---

🦋 ARGUMENTS 🦋

• from — the userspace buffer you're reading from, bestie. that's where the string lives 🫶
• count — the maximum number of bytes to read. cap it, don't let it run wild 💀
• array — the returned pointer to the sequence of integers. this is your main character output, no cap 👑

---

🌈 DESCRIPTION 🌈

so like, on success, array gets allocated and initialized with a sequence of integers that were extracted from from — plus one extra element at the very beginning of the sequence that specifies the count of integers. it's giving "count first, vibes after" ✨

and the important part, bestie: the caller takes responsibility for freeing array when it is no longer needed. yes, you. you're the one holding the kfree bag here 🫶 don't forget about it or that's a memory leak and we don't do those 😭
