NAME

       Incremental - obtain selection values

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

       void XtGetSelectionValuesIncremental(w, selection, tar-
       gets, 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.

XtGetSelectionValueIncrementXaTl(FX3UtXNGtCe)TtISOeNlSectionValueIncremental(3Xt)

DESCRIPTION
       The XtGetSelectionValueIncremental function is similar to
       XtGetSelectionValue except that the selection_callback
       procedure will be called repeatedly upon delivery of mul-
       tiple segments of the selection value.  The end of the
       selection value is indicated when selection_callback is
       called with a non-NULL value of length zero, which must
       still be freed by the client. If the transfer of the
       selection is aborted in the middle of a transfer (for
       example, because to timeout), the selection_callback pro-
       cedure is called with a type value equal to the symbolic
       constant XT_CONVERT_FAIL so that the requestor can dispose
       of the partial selection value it has collected up until
       that point. Upon receiving XT_CONVERT_FAIL, the requesting
       client must determine for itself whether or not a par-
       tially completed transfer is meaningful.

       The XtGetSelectionValuesIncremental function is similar to
       XtGetSelectionValueIncremental 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 XtGetSelectionValueIncremental.  The
       callback is called once with the corresponding client data
       for each target.  XtGetSelectionValuesIncremental does
       guarantee that all the conversions will use the same
       selection value becaues the ownership of the selection
       cannot change in the middle of the list, as would be when
       calling XtGetSelectionValueIncremental repeatedly.
