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 XGetMotionEvents().	This buffer may contain a finer granularity of events
  than is reported by MotionNotify events.

  There is no such macro as DisplayMotionBufferSize().
