/* getgraphmode 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, mode;
   char numname[80], modename[80];
   /* 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:");
exit(1);   /* terminate with an error code */
   midx = getmaxx() / 2;
   midy = getmaxy() / 2;
   /* get mode number and name strings */
   mode = getgraphmode();
   sprintf(numname, "%d is the current mode number.", mode);
   sprintf(modename, "%s is the current graphics mode.", getmodename
   /* display the information */
   settextjustify(CENTER_TEXT, CENTER_TEXT);
   outtextxy(midx, midy, numname);
   outtextxy(midx, midy+2*textheight("W"), modename);
   /* clean up */
   return 0;
