====Syntax of closegraph ====
#include
void closegraph(int wid=ALL_WINDOWS);
==== Description of closegraph ====
closegraph deallocates all memory allocated by the graphics system, then
restores the screen to the mode it was in before you called initgraph.
(The graphics system deallocates memory, such as the drivers, fonts, and
an internal buffer, through a call to _graphfreemem.)
==== Example of closegraph ====
/* closegraph example */
#include
#include
#include
#include
int main(void)
{
/* request autodetection */
int gdriver = DETECT, gmode, errorcode, 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;
/* output a message */
settextjustify(CENTER_TEXT, CENTER_TEXT);
outtextxy(x, y, "Press a key to close the graphics system:");
getch(); /* wait for a key */
/* closes down the graphics system */
closegraph();
printf("We're now back in text mode.\n");
printf("Press any key to halt:");
getch();
return 0;
