     The _getarcinfo function determines the endpoints in viewport
     coordinates of the most recently drawn arc or pie.
 
     If successful, the _getarcinfo function updates the <start> and
     <end> _xycoord structures to contain the endpoints (in viewport
     coordinates) of the arc drawn by the most recent call to one of
     the _arc or _pie functions.
     See: _xycoord
 
     In addition, <fillpoint> specifies a point from which a pie can be
     filled. This is useful for filling a pie in a color different from
     the border color. To change colors, use the _setcolor function
     after calling _getarcinfo. Use the coordinates in <fillpoint>,
     along with the color, as arguments for the _floodfill procedure.
 
     Return Value
 
     The _getarcinfo function returns a nonzero value if successful. If
     neither the _arc nor the _pie function has been successfully
     called since the last time the screen was cleared or a new
     graphics mode or viewport was selected, the _getarcinfo function
     returns 0.
