🌸 NAME 🌸

FcLangSetSubtract — Subtract langsets

✨ SYNOPSIS ✨

#include <fontconfig/fontconfig.h>

FcLangSet * FcLangSetSubtract (const FcLangSet *ls_a, const FcLangSet *ls_b);

🦋 DESCRIPTION 🦋

okay so here's the tea: it returns a set that includes only those languages found in ls_a but not in ls_b. So ls_a is your main character set, ls_b is the one getting gently removed from the group chat, and what's left is the set you get back. 💅

🎀 SINCE 🎀

this beauty has been around since version 2.9.0. periodt. 🫶
