XFillArc(display, d, gc,  x, y, width, height, angle1, angle2)
      Display *display;
      Drawable d;
      GC gc;
      int x, y;
      unsigned int width, height;
      int angle1, angle2;


display Specifies the connection to the X server.
d Specifies the drawable.
gc Specifies the GC.
x y Specify the x and y coordinates, which are relative to the origin of the drawable and specify the upper-left corner of the bounding rectangle.
width height Specify the width and height, which are the major and minor axes of the arc.
angle1 Specifies the start of the arc relative to the three-o'clock position from the center, in units of degrees * 64.
angle2 Specifies the path and extent of the arc relative to the start of the arc, in units of degrees * 64.


For each arc, XFillArc() fills the region closed by the infinitely thin path described by the specified arc and, depending on the arc-mode specified in the GC, one or two line segments. For ArcChord , the single line segment joining the endpoints of the arc is used. For ArcPieSlice , the two line segments joining the endpoints of the arc with the center point are used. For any given arc, .PN XFillArc does not draw a pixel more than once. If regions intersect, the intersecting pixels are drawn multiple times.

Both functions use these GC components: function, plane-mask, fill-style, arc-mode, subwindow-mode, clip-x-origin, clip-y-origin, and clip-mask. They also use these GC mode-dependent components: foreground, background, tile, stipple, tile-stipple-x-origin, and tile-stipple-y-origin.

XFillArc() can generate BadDrawable , BadGC , and BadMatch errors.


BadDrawable A value for a Drawable argument does not name a defined Window or Pixmap.
BadGC A value for a GContext argument does not name a defined GContext.
BadMatch An InputOnly window is used as a Drawable.
BadMatch Some argument or pair of arguments has the correct type and range but fails to match in some other way required by the request.
