NAME

XDisplayMotionBufferSize − get motion history buffer size. 

Synopsis

unsigned long XDisplayMotionBufferSize(display)

        Display *display;

Arguments

displaySpecifies a connection to an X server; returned from XOpenDisplay(). 

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().
