XtGetSelectionValueIncremental(3)XT FUNCTIONSXtGetSelectionValueIncremental(3)

NAME
       XtGetSelectionValueIncremental, XtGetSelectionValuesIncremental - ob-
       tain selection values

SYNTAX
       void XtGetSelectionValueIncremental(Widget w, Atom selection, Atom tar-
	      get, 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 re-
       ceiving XT_CONVERT_FAIL,	the requesting client must determine for it-
       self 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	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 because the ownership of
       the selection cannot change in the middle of the	list, as would be when
       calling XtGetSelectionValueIncremental repeatedly.
