#include <stdlib.h> 
#include <stdio.h> 
#include <conio.h> 

int main(void) 
{ 
   /* request auto detection */ 
   int gdriver = DETECT, gmode, errorcode; 
   int maxx, maxy; 
   char pattern[8] = {0x00, 0x70, 0x20, 0x27, 0x25, 0x27, 0x04, 0x04}; 

   /* initialize graphics and local variables */ 
   initgraph(&gdriver, &gmode, ""); 

   /* read result of initialization */ 
   errorcode = graphresult(); 
   if (errorcode != grOk)  /* an error occurred */ 
   { 
      printf("Graphics error: %sn", grapherrormsg(errorcode)); 
      printf("Press any key to halt:"); 
      getch(); 
      exit(1); /* terminate with an error code */ 
   } 

   maxx = getmaxx(); 
   maxy = getmaxy(); 
   setcolor(getmaxcolor()); 

   /* select a user defined fill pattern */ 
   setfillpattern(pattern, getmaxcolor()); 

   /* fill the screen with the pattern */ 
   bar(0, 0, maxx, maxy); 

   getch(); 

   /* get the current user defined fill pattern */ 
   getfillpattern(pattern); 

   /* alter the pattern we grabbed */ 
   pattern[4] -= 1; 
   pattern[5] -= 3; 
   pattern[6] += 3; 
   pattern[7] -= 4; 

   /* select our new pattern */ 
   setfillpattern(pattern, getmaxcolor()); 

   /* fill the screen with the new pattern */ 
   bar(0, 0, maxx, maxy); 

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