Syntax
void XtGetSelectionValue(w, selection, target, callback, client_data, time)
Widget w;
Atom selection;

XtSelectionCallbackProc callback;
XtPointer client_data;
Time time;
void XtGetSelectionValues(w, selection, targets, count, callback,
closures, time)
Widget w;
Atom selection;
Atom *targets;
int count;
XtSelectionCallbackProc callback;
XtPointer* closures;
Time time;
Arguments
callback Specifies the callback procedure that is to be called when the
selection value has been obtained.
clientdata
Specifies the argument that is to be passed to the specified
procedure when it is called.
clientdata
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 (either XAPRIMARY
or XASECONDARY).
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 tar-
gets. The effect is as if each target were specified in a separate call
to XtGetSelectionValue. The callback is called once with the corre-
sponding client data for each target. XtGetSelectionValues does guaran-
tee 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.
