SDL_OnApplicationDidEnterBackground - Man Page
Let iOS apps with external event handling report onApplicationDidEnterBackground.
Synopsis
#include <SDL3/SDL_system.h> void SDL_OnApplicationDidEnterBackground(void);
Description
This functions allows iOS apps that have their own event handling to hook into SDL to generate SDL events. This maps directly to an iOS-specific event, but since it doesn't do anything iOS-specific internally, it is available on all platforms, in case it might be useful for some specific paradigm. Most apps do not need to use this directly; SDL's internal event code will handle all this for windows created by SDL_CreateWindow!
Thread Safety
It is safe to call this function from any thread.
Availability
This function is available since SDL 3.2.0.
