getmaxmode

Returns the maximum mode number for the current driver.

Defined in header <graphics.h>

Syntax

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

Portability

Remarks

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 0.

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:");
      getchO;
      exit(l)                /* 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 */
getch();
closegraphO ;
return 0;
