Hi,
This program has been written in TurboC. I've heard DJGPP uses different Refs. I'd be thankful, if you can write in DJGPP.
Again, I'm looking forward,
Al.




/* Program to draw a Circle */

#include <graphics.h>
#include <stdlib.h>
#include <stdio.h>
#include <conio.h>

int main(void)
{

	/* request auto-detection */
	int gdriver = DETECT, gmode, errorcode;
	int midx, midy;
	int radius = 100;

	/* initialise graphics and local variables */
	initgraph(&gdriver, &gmode, "");

	/* read result of initialisation */
	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 */

	}

	midx = getmaxx() / 2;
	midy = getmaxy() / 2;
	setcolor(getmaxcolor());

	/* draw the circle */
	circle(midx, midy, radius);

	/* clean up */
	getch();
	closegraph();
	return 0;

}
