setfillstyle

Syntax

#include <graphics.h>
void setfillstyle(int pattern, int color);

Description

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).

Return Value

None.

Windows Notes

The winbgim version allows the color argument to be an ordinary BGI color (from 0 to 15) or an RGB color.
