XtGetSelectionRequest - retrieve the event that triggered the XtConvertSelectionProc

w         Specifies the widget.

       selection Specifies the selection being processed.

       request_id
                 Specifies the requestor id in the case of incremental selections, or NULL in the case of atomic
                 transfers.

XtGetSelectionRequest  may  only  be called from within an XtConvertSelectionProc procedure and returns a
       pointer to the SelectionRequest event that caused the conversion procedure  to  be  invoked.   Request_id
       specifies  a  unique  id  for  the individual request in the case that multiple incremental transfers are
       outstanding.  For atomic transfers, request_id must be specified as NULL. If no SelectionRequest event is
       being processed for the specified widget, selection, and request_id, XtGetSelectionRequest returns NULL.
