Hallo Welt mit KallistiOS

Das folgende kleine Programm zeigt einen Hallo Welt-Schriftzug auf dem Bildschirm an.

#include <kos.h>

 extern uint8 romdisk[];

/* These macros tell KOS how to initialize itself. All of this initialization
  happens before main() gets called, and the shutdown happens afterwards. So
  you need to set any flags you want here. Here are some possibilities:

  INIT_NONE		-- don't do any auto init
  INIT_IRQ		-- Enable IRQs
  INIT_THD_PREEMPT	-- Enable pre-emptive threading
  INIT_NET		-- Enable networking (doesn't imply lwIP!)
  INIT_MALLOCSTATS	-- Enable a call to malloc_stats() right before shutdown

  You can OR any or all of those together. If you want to start out with
  the current KOS defaults, use INIT_DEFAULT (or leave it out entirely). */
KOS_INIT_FLAGS(INIT_DEFAULT | INIT_MALLOCSTATS);

/* And specify a romdisk, if you want one (or leave it out) */
KOS_INIT_ROMDISK(romdisk);

/* Your program's main entry point */
int main(int argc, char **argv) {
	/* The requisite line */
	printf("\nHello world!\n\n");

	return 0;
