FcLangSetHash(3)

💅 FcLangSetHash(3) — the vibe check for your langsets

okay so bestie, welcome to FcLangSetHash(3), section 3 of the manual, and honestly? it's giving tiny-but-iconic. one function, does exactly one thing, no drama. 🎀

---

✨ NAME ✨

FcLangSetHash — literally just returns a hash value for a langset. that's it. that's the whole job. 🫶

---

🌸 SYNOPSIS 🌸

#include <fontconfig/fontconfig.h>

FcChar32 FcLangSetHash (const FcLangSet *ls);

so you include <fontconfig/fontconfig.h> (yes, that exact path, don't get creative 💀), and you call FcLangSetHash with a const FcLangSet * named ls, and it hands you back an FcChar32. clean. simple. slay. ✨

---

🦋 DESCRIPTION 🦋

so here's the tea ☕ — FcLangSetHash returns a value that depends solely on the languages supported by ls. like, nothing else. no sneaky extra inputs, no side quests. 👑

the practical upshot? any langset that equals ls is gonna give you the same result from FcLangSetHash. same langs, same hash. periodt. 💖

⚠️ but bestie, listen — the reverse does NOT hold. two langsets with the same hash value may not be equal. so do not come for me with "but the hashes match!!" because that is not proof of anything, ngl. 🙈 hash collisions are just a thing, iykyk. 🧚

🌈 tl;dr, the group-chat recap 🌈

• returns a hash value for a langset ✅
• depends only on the languages supported by ls ✅
• equal langsets → same hash, always ✅
• same hash → does not mean equal langsets ❌ (no cap) 💀
