==== Example of graphdefaults ====
<code c>
/* graphdefaults example */

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

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

   /* 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 */
   }

   maxx = getmaxx();
   maxy = getmaxy();

   /* output line with nondefault settings */
   setlinestyle(DOTTED_LINE, 0, 3);
   line(0, 0, maxx, maxy);
   outtextxy(maxx/2, maxy/3, "Before default values are restored.");
   getch();

   /* restore default values for everything */
   graphdefaults();

   /* clear the screen */
   cleardevice();



   /* output line with default settings */
   line(0, 0, maxx, maxy);
   outtextxy(maxx/2, maxy/3, "After restoring default values.");

   /* clean up */
   getch();
   closegraph();
   return 0;
