## fillpoly

### Syntax of fillpoly

```#include <graphics.h>
void fillpoly(int numpoints, int *polypoints);
```

### Description of fillpoly

```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.```

### Example of fillpoly

```/* fillpoly example */

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

int main(void)
{
/* request autodetection */
int gdriver = DETECT, gmode, errorcode;
int i, maxx, maxy;

/* our polygon array */
int poly[8];

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

/* read result of initialization */
errorcode = graphresult();
if (errorcode != grOk) {  /* an error occurred */
printf("Graphics error: %s\n", grapherrormsg(errorcode));

printf("Press any key to halt:");
getch();
exit(1);   /* terminate with an error code */
}

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

poly[0] = 20; /* first vertex */
poly[1] = maxy / 2;
poly[2] = maxx - 20;/* second vertex */
poly[3] = 20;
poly[4] = maxx - 50;/* third vertex */
poly[5] = maxy - 20;
poly[6] = maxx / 2; /* fourth, fillpoly automatically */
poly[7] = maxy / 2; /* closes the polygon */

/* loop through the fill patterns */
for (i=EMPTY_FILL; i<USER_FILL; i++) {
/* set fill pattern */
setfillstyle(i, getmaxcolor());

/* draw a filled polygon */
fillpoly(4, poly);
getch();
}

/* clean up */
closegraph();
return 0;
}```
