XDisplayMotionBufferSize()			    XDisplayMotionBufferSize()

Name
  XDisplayMotionBufferSize – get motion history buffer size.

Synopsis
  unsigned long XDisplayMotionBufferSize(display)
	     Display *display;

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

Returns
  The size in events of the buffer.

Description
  XDisplayMotionBufferSize() queries the approximate  maximum  number  of
  elements in the motion history buffer.

  The  X server may, but is not required to, retain the recent history of
  the pointer motion in a motion history buffer.  If there is  no  motion
  history buffer, XDisplayMotionBufferSize() returns zero.

  Motion  history  buffers  were  implemented for the first time in MIT's
  sample servers in Release 5, but some earlier	 releases  of  commercial
  servers may provide support.

  An  application  gains access to the motion history buffer with XGetMo‐
  tionEvents().	 This buffer may contain a finer  granularity  of  events
  than is reported by MotionNotify events.

  There is no such macro as DisplayMotionBufferSize().
