NAME
SDL_OnApplicationDidReceiveMemoryWarning - Let iOS apps with external event handling report
onApplicationDidReceiveMemoryWarning.
SYNOPSIS
#include <SDL3/SDL_system.h>
void SDL_OnApplicationDidReceiveMemoryWarning(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.
