c:graphics.h:getgraphmode

getgraphmode

Syntax of getgraphmode

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

Description of getgraphmode

Your program must make a successful call to initgraph before calling
getgraphmode.
The enumeration graphics_mode, defined in graphics.h, gives names for the
predefined graphics modes. For a table listing these enumeration values,
refer to the description for initgraph.

Example of getgraphmode

/* 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:");
getch();
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
(mode));
 
   /* display the information */
   settextjustify(CENTER_TEXT, CENTER_TEXT);
   outtextxy(midx, midy, numname);
 
   outtextxy(midx, midy+2*textheight("W"), modename);
 
   /* clean up */
   getch();
   closegraph();
   return 0;
}
