     NAME
          XtGetSelectionValue, XtGetSelectionValues - obtain selection
          values

     SYNTAX
          void XtGetSelectionValue(w, selection, target, callback,
          client_data, time)
                Widget w;
                Atom selection;
                Atom target;
                XtSelectionCallbackProc callback;
                XtPointer client_data;
                Time time;

          void XtGetSelectionValues(w, selection, targets, count,
          callback, client_data, time)
                Widget w;
                Atom selection;
                Atom *targets;
                int count;
                XtSelectionCallbackProc callback;
                XtPointer client_data;
                Time time;

     ARGUMENTS
          callback  Specifies the callback procedure that is to be
                    called when the selection value has been obtained.

          client_data
                    Specifies the argument that is to be passed to the
                    specified procedure when it is called.

          client_data
                    Specifies the client data (one for each target
                    type) that is passed to the callback procedure
                    when it is called for that target.

          count     Specifies the length of the targets and
                    client_data lists.

          selection Specifies the particular selection desired (that
                    is, primary or secondary).

          target    Specifies the type of the information that is
                    needed about the selection.

          targets   Specifies the types of information that is needed
                    about the selection.

          time      Specifies the timestamp that indicates when the
                    selection value is desired.
          w         Specifies the widget that is making the request.

     DESCRIPTION
          The XtGetSelectionValue function requests the value of the
          selection that has been converted to the target type. The
          specified callback will be called some time after
          XtGetSelectionValue is called; in fact, it may be called
          before or after XtGetSelectionValue returns.

          The XtGetSelectionValues function is similar to
          XtGetSelectionValue except that it takes a list of target
          types and a list of client data and obtains the current
          value of the selection converted to each of the targets.
          The effect is as if each target were specified in a separate
          call to XtGetSelectionValue.  The callback is called once
          with the corresponding client data for each target.
          XtGetSelectionValues does guarantee that all the conversions
          will use the same selection value because the ownership of
          the selection cannot change in the middle of the list, as
          would be when calling XtGetSelectionValue repeatedly.
