SDL_isinff(3)

SDL_isinff(3) 💖

okay bestie, welcome to the SDL3 FUNCTIONS corner of the manual, this one's a lil baby function but she's important, fr fr 🎀

---

✨ NAME ✨

SDL_isinff — tells you whether a value is infinity or not, that's it, that's the whole job 💅

---

🌸 SYNOPSIS 🌸

#include <SDL3/SDL_stdinc.h>

int SDL_isinff(float x);

like look at her, one include, one function call, no drama, we love a low-maintenance icon 👑

---

🦋 FUNCTION PARAMETERS 🦋

• x — a floating point value. just. a float. hand it over and she'll vibe check it for you 🫶

---

💜 RETURN VALUE 💜

Returns non-zero if the value is infinity, and 0 otherwise. so it's giving "yes bestie" or "no bestie", very binary, very decisive, no in-between nonsense ✨

ngl it's not literally returning "true/false", it's non-zero vs 0, so don't go comparing it to 1 and expecting a promise, okay? 😭

---

🧚 THREAD SAFETY 🧚

It is safe to call this function from any thread. yes queen, no locks, no mutexes, no stress, call her from wherever, she does not care 💖

---

⭐ AVAILABILITY ⭐

This function is available since SDL 3.2.0. so if you're on something older... bestie, upgrade, I'm begging 🙈
