NAME
       al_iphone_program_has_halted - Allegro 5 API

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.
