FcCharSetDestroy(3)

💅 FcCharSetDestroy(3) — the FcCharSetDestroy page, bestie ✨

Okay so real quick context before we get into it: this is section 3 of the manual, and the whole page is literally called FcCharSetDestroy. Tiny page, huge slay. Let's go 🎀

💖 NAME 💖

FcCharSetDestroy — destroy a character set, fr fr

✨ SYNOPSIS ✨

First thing you gotta do is pull in the header, no cap:

#include <fontconfig/fontconfig.h>

And here's the actual function signature, character for character:

void FcCharSetDestroy (FcCharSet *fcs);

🌸 DESCRIPTION 🌸

So FcCharSetDestroy does one very specific little thing and it does it well 💅 — it decrements the reference count of fcs.

That's it. That's the whole gig. But here's the part that actually matters 👀 — if that reference count becomes zero, then all the memory that's being referenced gets freed. Like, gone. All of it. Freed. 🫶

Not me about to stress this: it's a reference count situation, so you're not necessarily nuking memory every time you call this. Zero is the magic number. When it hits zero, the memory is freed. When it doesn't, it isn't. iykyk 💀
