<code c>
/* cleardevice example */

#include <graphics.h>
#include <stdlib.h>
#include <stdio.h>
#include <conio.h>

int main(void)
{
   /* request autodetection */
   int gdriver = DETECT, gmode, errorcode;
   int midx, midy;

   /* initialize graphics and local variables */
   initgraph(&gdriver, &gmode, "");

   /* read result of initialization */
   errorcode = graphresult();
   if (errorcode != grOk) {    /* an error occurred */
printf("Graphics error: %s\n", grapherrormsg(errorcode));

printf("Press any key to halt:");
getch();
exit(1);     /* terminate with an error code */
   }

   midx = getmaxx() / 2;
   midy = getmaxy() / 2;
   setcolor(getmaxcolor());

   /* for centering screen messages */
   settextjustify(CENTER_TEXT, CENTER_TEXT);

   /* output a message to the screen */
   outtextxy(midx, midy, "Press any key to clear the screen:");

   getch();   /* wait for a key */
   cleardevice();   /* clear the screen */

   /* output another message */
   outtextxy(midx, midy, "Press any key to quit:");
   /* clean up */
   getch();
   closegraph();
   return 0;
