SDL_ONAPPLICATIONWILLENTERFOREGROUND(3)

💖 SDL_OnApplicationWillEnterForeground 💖

okay bestie so real talk: this is a page from the SDL3 FUNCTIONS manual, and the function we're gagged about today is SDL_OnApplicationWillEnterForeground. she's giving "iOS apps with external event handling, come get your onApplicationWillEnterForeground report" energy. periodt. ✨

🌸 NAME 🌸

SDL_OnApplicationWillEnterForeground — the way that this lets iOS apps with external event handling report onApplicationWillEnterForeground. no cap, that's literally the whole job description. 🎀

---

🦋 SYNOPSIS 🦋

#include <SDL3/SDL_system.h>

void SDL_OnApplicationWillEnterForeground(void);

look at her. no arguments, no return value, just vibes and a <SDL3/SDL_system.h> include. lowkey iconic. 💅

---

✨ DESCRIPTION ✨

so here's the tea, bestie: this function lets iOS apps that have their own event handling hook into SDL so SDL can generate SDL events. it maps directly to an iOS-specific event, but — and this is the important part — since it doesn't do anything iOS-specific internally, it's available on all platforms, just in case it might be useful for some specific paradigm. so even if you're not on iOS, she's still there for you. 🫶

now the big one: most apps do not need to use this directly. SDL's internal event code will handle all this for windows created by SDL_CreateWindow! so like, don't come for her unless you actually need to, okay? main character energy is calling SDL_CreateWindow and letting SDL do its thing. 💀

🧚 THREAD SAFETY 🧚

it is safe to call this function from any thread. queen behavior, honestly. multi-threaded slay. 🔥

---

💜 AVAILABILITY 💜

this function is available since SDL 3.2.0. so if you're on something older... babe, upgrade. 🙈

---

okay and finally, the cute lil sign-off: this whole page comes to you from Simple Directmedia Layer, version SDL 3.4.18, filed under the SDL_OnApplica...terForeground(3) manual page. that's the source, that's the version, that's the whole entire vibe. go forth and handle your events, bestie. 🌈💖🦋✨
