FcStrBuildFilename(3)

💅 FcStrBuildFilename(3) — the fontconfig glow-up

okay bestie, so this whole page is about FcStrBuildFilename from the fontconfig manual, and it's genuinely one of the most useful little functions ever. it builds file paths for you, no cap. let's get into it 🫶

---

✨ NAME ✨

FcStrBuildFilename — literally just concatenating strings together as a file path. that's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

#include <fontconfig/fontconfig.h>

FcChar8 * FcStrBuildFilename (const FcChar8 *path, ...);

look at that signature, it's giving main character energy 🔥

🦋 DESCRIPTION 🦋

so here's the tea: this function creates a filename out of the elements of strings you hand it, treating them like file paths, and it concatenates them together using the appropriate file separator. yes, the appropriate file separator — it handles that for you so you don't have to think about it. iconic behavior honestly 💅

the arguments must be null-terminated. that's non-negotiable, bestie — null-terminate your args or it's not gonna go well 🙈

and the return? it gives you newly-allocated memory. so like, it's yours now, you own it, and you should free it when it's no longer needed. not me reminding you to free your memory... but also yes, me reminding you to free your memory 😭💀

foreal foreal: it returns newly-allocated memory. free it when you're done or that's a leak, and leaks are not the vibe. 🚫
