举例：
#include <graphics.h>
#include <stdlib.h>
#include <stdio.h>
#include <conio.h>
int main(void)
{
int gdriver = DETECT, gmode, errorcode;
int maxx, maxy;
int poly[10];
initgraph(&gdriver, &gmode, );
errorcode = graphresult();
if (errorcode != grOk)
{
printf("Graphics error: %s
",grapherrormsg(errorcode));
printf("Press any key to halt:");
getch();
exit(1);
}
maxx = getmaxx();
maxy = getmaxy();
poly[0] = 20;
poly[1] = maxy / 2;
poly[2] = maxx - 20;
poly[3] = 20;
poly[4] = maxx - 50;
poly[5] = maxy - 20;
poly[6] = maxx / 2;
poly[7] = maxy / 2;
poly[8] = poly[0];
poly[9] = poly[1];
drawpoly(5, poly);
getch();
closegraph();
return 0;
}
