函数名: closegraph

功 能: 关闭图形系统

用 法: void far closegraph(void);

程序例:

#include

#include

#include

#include

int main(void)

{

/* request auto detection */

int gdriver = DETECT, gmode, errorcode;

int x, y;

/* initialize graphics mode */

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 */

}

x = getmaxx() / 2;

y = getmaxy() / 2;

}

x = getmaxx() / 2;

y = getmaxy() / 2;

/* output a message */

settextjustify(CENTER_TEXT, CENTER_TEXT);

outtextxy(x, y, "Press a key to close the graphics system:");

/* wait for a key */

getch();

/* closes down the graphics system */

closegraph();

printf("We're now back in text mode.\n");
