Sample Code


MEIInt64 newTargetPos;


returnValue = meiPlatformMemoryGet64(axis->platform,
                                     &newTargetPos,
                                     &axis->Axis->TC.CommandPosition);

if (returnValue == MPIMessageOK) {
    returnValue = meiPlatformMemorySet64(axis->platform,
                                         &axis->Axis->TC.TargetPosition,
                                         &newTargetPos);
