XFillArcs()															       XFillArcs()

Name
  XFillArcs - fill multiple arcs.

Synopsis
  XFillArcs(display, drawable, gc, arcs, narcs)
	Display *display;
	Drawable drawable;
	GC gc;
	XArc *arcs;
	int narcs;

Arguments
  display  Specifies a connection to an X server; returned from XOpenDisplay().

  drawable
	   Specifies the drawable.

  gc	   Specifies the graphics context.

  arcs	   Specifies a pointer to an array of arc definitions.

  narcs    Specifies the number of arcs in the array.

Description
  For each arc, XFillArcs() fills the region closed by the specified arc and one or two line segments, depending on the arc_mode specified in
  the GC.  It does not draw the complete outlines of the arcs, but some pixels may overlap.

  The arc forms one boundary of the area to be filled.	The other boundary is determined by the arc_mode in the GC.  If the arc_mode  in  the
  GC  is  ArcChord, the single line segment joining the endpoints of the arc is used.  If ArcPieSlice, the two line segments joining the end-
  points of the arc with the center point are used.  The arcs are filled in the order listed in the array.  For any given arc,	no  pixel  is
  drawn more than once.  If filled arcs intersect, pixels will be drawn multiple times.

  In R4 and earlier there is a limit to the number of rectangles that can be drawn in a single call, based on the maximum request size, which
  varies according to the server.  In R5, Xlib chops your call into as many protocol requests as required.  To determine how many  rectangles
  you can draw in a single call in R4, you find out your server's maximum request size using XMaxRequestSize().  Subtract three and divide by
  three, and this is the maximum number of arcs you can fill in a single XFillArcs() call.

  XFillArcs() use these graphics context components: function, plane_mask, fill_style, arc_mode, subwindow_mode,  clip_x_origin,  clip_y_ori-
  gin,	and  clip_mask.   This	function  also	uses these graphics context mode-dependent components: foreground, background, tile, stipple,
  ts_x_origin,								 and								ts_y_
  origin.
