 +====Syntax of setfillstyle ==== 
 + <code c>
 +#include <graphics.h>
 +void setfillstyle(int pattern, int color);
 +  </code>
 +
 +
 +==== Description of setfillstyle ==== 
 +<code c>
 +setfillstyle sets the current fill pattern and fill color. To set a user-
 +defined fill pattern, do not give a pattern of 12 (USER_FILL) to
 +setfillstyle; instead, call setfillpattern.
 +If invalid input is passed to setfillstyle, graphresult returns -1
 +(grError), and the current fill pattern and fill color remain unchanged.
 +Note: The EMPTY_FILL style is like a solid fill using the current
 +background color (which is set by setbkcolor).
