 +====Syntax of setfillpattern ==== 
 + <code c>
 +#include <graphics.h>
 +void setfillpattern(char *upattern, int color);
 +  </code>
 +
 +
 +==== Description of setfillpattern ==== 
 +<code c>
 +setfillpattern is like setfillstyle, except that you use it to set a
 +user-defined 8x8 pattern rather than a predefined pattern.
 +upattern is a pointer to a sequence of 8 bytes, with each byte
 +corresponding to 8 pixels in the pattern. Whenever a bit in a pattern
 +byte is set to 1, the corresponding pixel is plotted.
