  </code>


==== Description of line ====

line draws a line in the current color, using the current line style and
thickness between the two points specified, (x1,y1) and (x2,y2), without
updating the current position (CP).
</code>


==== Example of line ====
<code c>
/* line example */

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

int main(void)
{

   /* request autodetection */
   int gdriver = DETECT, gmode, errorcode;
   int xmax, ymax;

   /* initialize graphics and local variables */
   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);
   }

   setcolor(getmaxcolor());
   xmax = getmaxx();
   ymax = getmaxy();

   /* draw a diagonal line */
   line(0, 0, xmax, ymax);

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