#include "graphics.h"
void delay(int millisec);
 

The delay function is available in the winbgim implementation of BGI
graphics. You do not need to include conio.h; just include graphics.h.
The function pauses the computation for the the specified number of
milliseconds.

/* delay example */
 
#include "graphics.h"
 
int main(void)
{
   int midx, midy, i;
 
   /* initialize the window size */
   initwindow(100, 100);
 
   midx = getmaxx() / 2;
   midy = getmaxy() / 2;
 
   /* loop through the fill patterns with 4 second delays */
   for (i=SOLID_FILL; i<USER_FILL; i++) {
/* set the fill style */
setfillstyle(i, getmaxcolor());
 
/* draw the bar */
bar(midx-50, midy-50, midx+50, midy+50);
delay(4000);
   }
 
   /* clean up */
   closegraph();
   return 0;
 
}
