✨ idn_free(3) ✨

okay bestie, welcome to libidn's very own little memory-releasing moment 💖 this is the manual page for idn_free, and yes it's short, but it's giving essential so let's get into it 🫶

🎀 NAME 🎀

idn_free — it's an API function, and its whole job is freeing memory 🧚

🌸 SYNOPSIS 🌸

#include <idn.h>

void idn_free(void * ptr);

periodt. that's the whole signature, no cap ✨

🦋 ARGUMENTS 🦋

  • void * ptr — the memory region you want to deallocate, or NULL. that's it, that's the vibe 💅

💖 DESCRIPTION 💖

So what it does is deallocate a memory region by calling free(). and if ptr is NULL, literally nothing happens — no operation is performed, no drama, we just move on 🙈

Now here's the tea ☕ normally, applications de-allocate strings that were allocated by libidn by calling free() directly. simple, right? but under Windows, different parts of the same application may use different heap memory 😭 and when that happens, it is important to deallocate memory within the same module that allocated it. this function makes that possible — she's the fix, she's the moment, she's the main character energy 👑

ngl this one is small but she's carrying a whole Windows-compatibility situation on her back 💀
