XtGetSelectionValue(), XtGetSelectionValues() - obtain selection values
void XtGetSelectionValue (Widget w, Atom selection,
Atom target,
XtSelectionCallbackProc callback,
XtPointer client_data, Time time)
void XtGetSelectionValues (Widget w, Atom selection,
Atom *targets, int count,
XtSelectionCallbackProc callback,
XtPointer client_data, Time time)
The XtGetSelectionValue(3) 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(3) is called; in fact, it can be called before or after XtGetSelectionValue(3) returns.
The XtGetSelectionValues(3) function is similar to XtGetSelectionValue(3) 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 XtGetSelectionValue(3). The callback is called once with the corresponding client data for each target. XtGetSelectionValues(3) 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 XtGetSelectionValue(3) repeatedly.
