kfree_strarray(9)

✨ kfree_strarray — the kernel API manual, bestie edition ✨

okay so you're in the Kernel API Manual and the function we're talking about is kfree_strarray(9). yes that's the title, yes I'm telling you up front, we're doing this properly 💅

---

🌸 NAME 🌸

kfree_strarray — frees a number of dynamically allocated strings that are chilling inside an array, plus the array itself. like, the whole thing goes 🫶

---

🦋 SYNOPSIS 🦋

void kfree_strarray (char **array , size_t n );

---

💖 ARGUMENTS 💖

• array — the dynamically allocated array of strings you want to free. it's a char **, it's living its best life on the heap, and now it's gotta go ✨
• n — the number of strings to free, counting from the beginning of the array. so like, the first n ones, in order, no skipping 🙈

---

🎀 DESCRIPTION 🎀

okay so there are two very valid use-cases here and I need you to not panic about either of them:

1. passing a non-NULL array together with n == 0 — totally valid, no notes 💅
2. passing a NULL array — also valid, also fine, we love a flexible API

and if array is NULL? the function literally does nothing. that's it. that's the whole vibe check. nothing happens, no crash, no drama, we simply move on 🧚
