SYNOPSIS
#include <allegro5/allegro_iphone.h>
void al_iphone_program_has_halted(void)DESCRIPTION
Multitasking on iOS is different than on other platforms. When an
application receives an ALLEGRO_DISPLAY_SWITCH_OUT or ALLEGRO_DIS‐
PLAY_CLOSE event on a multitasking-capable device, it should cease all
activity and do nothing but check for an ALLEGRO_DISPLAY_SWITCH_IN
event. To let the iPhone driver know that you've ceased all activity,
call this function. You should call this function very soon after
receiving the event telling you it's time to switch out (within a cou‐
ple milliseconds). Certain operations, if done, will crash the program
after this call, most notably any function which uses OpenGL. This
function is needed because the "switch out" handler on iPhone can't
return until these operations have stopped, or a crash as described
before can happen.
