NAME
       XtGetSelectionValueIncremental, XtGetSelectionValuesIncremental -
       obtain selection values

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

       void XtGetSelectionValuesIncremental(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 XtGetSelectionValueIncremental function is similar to XtGetSelec-
       tionValue except that the selection_callback procedure will be called
       repeatedly upon delivery of multiple 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 mid-
       dle of a transfer (for example, because to timeout), the selec-
       tion_callback procedure is called with a type value equal to the sym-
       bolic 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 partially completed transfer is meaningful.

       The XtGetSelectionValuesIncremental function is similar to XtGet-
       SelectionValueIncremental except that it takes a list of target types
       and a list of client data and obtains the current value of the selec-
       tion converted to each of the targets.  The effect is as if each tar-
       get were specified in a separate call to XtGetSelectionValue-
       Incremental.  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
       because the ownership of the selection cannot change in the middle of
       the list, as would be when calling XtGetSelectionValueIncremental
       repeatedly.
