XtGetSelectionValueIncremental, XtGetSelectionValues-
Incremental - obtain selection values
void XtGetSelectionValueIncremental(Widget w, Atom selec-
tion, Atom target, XtSelectionCallbackProc callback,
XtPointer client_data, Time time);
void XtGetSelectionValuesIncremental(Widget w, Atom selec-
tion, Atom *targets, int count, XtSelectionCallbackProc
callback, XtPointer client_data, Time time);
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.
The XtGetSelectionValueIncremental function is similar to
XtGetSelectionValue except that the selection_callback pro-
cedure 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 middle of a transfer (for example, because to timeout),

the selection_callback procedure 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 partially 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 tar-
gets. The effect is as if each target were specified in a
separate call to XtGetSelectionValueIncremental. The call-
back 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 XtGetSelection-
ValueIncremental repeatedly.
