FcConfigSetRescanInterval(3)

💅 FcConfigSetRescanInterval(3) — like, the fontconfig rescan interval situation 🎀

okay bestie, welcome to FcConfigSetRescanInterval(3), a fontconfig manual page and honestly a little cutie. she's short, she's sweet, she controls how often fontconfig wakes up and checks stuff. let's get into it ✨

---

🌸 NAME 🌸

FcConfigSetRescanInterval — sets the config rescan interval. that's it, that's the whole gig 🫶

---

✨ SYNOPSIS ✨

#include <fontconfig/fontconfig.h>

FcBool FcConfigSetRescanInterval (FcConfig *config, int rescanInterval);

look at her go. one include, one function, zero drama 💖

---

🦋 DESCRIPTION 🦋

so basically this sets the rescan interval. like, the interval for rescanning. iconic behavior tbh.

it returns FcFalse if the interval can't be set — and the reason for that is an allocation failure (yes, the malloc-adjacent heartbreak 😭). otherwise it returns FcTrue, and we love that for us 👑

an interval setting of zero disables automatic checks entirely. no automatic checks. none. she's off duty 💀

and if config is NULL, the current configuration is used. default queen behavior, no notes 💅

ngl, keep the NULL thing in mind — it's not an error, it's just "use whatever config is current" 🎀
