<hr><a name="_details"></a><h2>Detailed Description</h2>
This file provides functions similar to miPointerGetMotionEvents and miPointerPutMotionEvents, with the exception that devices with more than two axes are fully supported. These routines may be used only for motion buffers for extension devices, and are <em>not</em> compatible replacements for the mi routines.<hr><h2>Function Documentation</h2>

<p>
This routine performs the same function as <em>miPointerGetMotionEvents</em>: the events in the motion history that are between the start and stop times (in mS) are placed in the coords vector, and the count of the number of items so placed is returned. This routine is called from dix/devices.c so that coords can hold valuator-&gt;numMotionEvents events. This routine is called from <em>Xi/gtmotion</em>.c with coords large enough to hold the same number of events in a variable-length extended <em>xTimecoord</em> structure. This provides sufficient data for the <em>XGetDeviceMotionEvents</em> library call, and would be identical to <em>miPointerGetMotionEvents</em> for devices with only 2 axes (i.e., core pointers) if <em>xTimecoord</em> used 32bit integers.<p>
Because DMX uses the mi* routines for all core devices, this routine only has to support extension devices using the polymorphic coords. Because compatibility with miPointerGetMotionEvents is not possible, it is not provided.     </td>
