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().
