drawpoly

Syntax
```
#include <graphics.h>

void drawpoly(int numpoints, int *polypoints);

```
Description
drawpoly draws a polygon with numpoints points, using the current line style and 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.

In order to draw a closed figure with n vertices, you must pass n + 1 coordinates to drawpoly where the nth coordinate is equal to the 0th.

Return Value
None.

fillpoly
floodfill
graphresult

Example
```
/* drawpoly example */

#include <graphics.h>

#include <stdlib.h>

#include <stdio.h>

#include <conio.h>

int main(void)

{

/* request autodetection */

int gdriver = DETECT, gmode, errorcode;

int maxx, maxy;

int poly[10];   /* our polygon array */

/* 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 vertex */

poly[7] = maxy / 2;

poly[8] = poly[0];      /* drawpoly doesn't automatically close */

poly[9] = poly[1];      /* the polygon, so we close it */

drawpoly(5, poly);   /* draw the polygon */

/* clean up */

getch();

closegraph();

return 0;
