Syntax of getmaxmode

#include <graphics.h>
int getmaxmode(void);

Description of getmaxmode

getmaxmode lets you find out the maximum mode number for the currently
loaded driver, directly from the driver. This gives it an advantage over
getmoderange, which works for Borland drivers only. The minimum mode is

Example of getmaxmode

/* getmaxmode 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;
   char modestr[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;
   /* grab the mode info. and convert it to a string */
   sprintf(modestr, "This driver supports modes 0..%d", getmaxmode());
   /* display the information */
   settextjustify(CENTER_TEXT, CENTER_TEXT);
   outtextxy(midx, midy, modestr);
   /* clean up */
   return 0;
