EDSDK - Request AutoFocus without stopping liveview image retrieval

Question

I would like to be able to autofocus while retrieving images from the liveview.

In my case, when I autofocus, the image retrieval stops and starts again once I get the autofocus command back. I autofocus the camera using the :

SendCommand(kEdsCameraCommand_PressShutterButton, kEdsCameraCommand_ShutterButton_Halfway);

Is this possible? This function is available via Canon's EOS Utility application.

Thank you for taking the time to read this.
