     NAME
          XtGetSelectionParameters - retrieve target parameters for a
          selection request with a single target

     SYNTAX
          void XtGetSelectionParameters(owner, selection, request_id,
          type_return, value_return, length_return, format_return)
                Widget owner;
                Atom selection;
                XtRequestId request_id;
                Atom* type_return;
                XtPointer* value_return;
                unsigned long* length_return;
                int* format_return;

     ARGUMENTS
          owner     Specifies the widget that owns the specified
                    selection.

          selection Specifies the selection being processed.

          request_id
                    Specifies the requestor id in the case of
                    incremental selections, or NULL in the case of
                    atomic transfers.

          type_return
                    Specifies a pointer to an atom in whcih the
                    property type of the parameters will be stored.

          value_return
                    Specifies a pointer into which a pointer to the
                    parameters are to be stored. A NULL will be stored
                    if no parameters accompany the request.

          length_return
                    Specifies a pointer into which the number of data
                    elements in value_return of size indicated by
                    format_return will be stored.

          format_return
                    Specifies a pointer into which the size in bits of
                    the parameter data in the elements of value_return
                    will be stored.

     DESCRIPTION
          XtGetSelectionParameters may only be called from within an
          XtConvertSelectionProc or from within the last call to an
          XtConvertSelectionIncrProc with a new request_id.
