====Syntax of getmoderange ==== 
 <code c>
#include <graphics.h>
void getmoderange(int graphdriver, int *lomode, int *himode);
  </code>


==== Description of getmoderange ==== 
<code c>
getmoderange gets the range of valid graphics modes for the given
graphics driver, graphdriver. The lowest permissible mode value is
returned in *lomode, and the highest permissible value is *himode. If
graphdriver specifies an invalid graphics driver, both *lomode and
*himode are set to -1. If the value of graphdriver is -1, the currently
loaded driver modes are given.

==== Example of getmoderange ====
<code c>
/* getmoderange 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;
   int low, high;
   char mrange[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:");
   getch();
   exit(1);/* terminate with an error code */
   }

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

   /* get the mode range for this driver */
   getmoderange(gdriver, &low, &high);

   /* convert mode range info. into strings */
   sprintf(mrange, "This driver supports modes %d..%d", low, high);

   /* display the information */
   settextjustify(CENTER_TEXT, CENTER_TEXT);
   outtextxy(midx, midy, mrange);


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