fillpoly

Syntax

#include <graphics.h>

void fillpoly(int numpoints, int *polypoints);

Description

fillpoly draws the outline of a polygon with numpoints points in the current line style and color (just as drawpoly does), then fills the polygon using the current fill pattern and fill color.

polypoints points to a sequence of (numpoints * 2) integers. Each pair of integers gives the x- and y-coordinates of a point on the polygon.

Return Value

None.

   }

   poly[4] = maxx - 50;      /* third vertex */

   poly[6] = maxx / 2;       /* fourth, fillpoly automatically */

   poly[7] = maxy / 2;       /* closes the polygon */
