XtSetSelectionParameters - specify target parameters for a selection
       request with a single target


       #include <X11/Intrinsic.h>

       void XtSetSelectionParameters(Widget requestor, Atom selection, Atom
              type, XtPointer value, unsigned long length, int format);


       requestor Specifies the widget making the request.  Must be of class
                 Core or any subclass thereof.

       selection Specifies the atom that names the selection.

       type      Specifies the type of the property in which the parameters
                 will be passed.

       value     Specifies a pointer to the parameters.

       length    Specifies the number of elements containing data in value,
                 each element of a sized indicated by format.

       format    Specifies the size in bits of the data in the elements of


       The specified parameters will be copied and stored in a new property of
       the specified type and format on the requestor's window.  To initiate a
       selection request with a target and these parameters, a subsequent call
       to XtGetSelectionValue or to XtGetSelectionValueIncremental specifying
       the same requestor widget and selection atom will generate a ConvertSe-
       lection request referring referring to the property containing the
       parameters.  If XtSetSelectionParameters is called more than once with
       the same widget and selection without a call to specify a request, the
       most recently specified parameters are used in the subsequent request.

       The possible values of format may be 8, 16, or 32.  If the format is 8,
       the elements of value are assumed to be sizeof(char); if 16,
       sizeof(short); if 32, sizeof(long).

       To generate a MULTIPLE target request with parameters for any of the
       multiple targets of the selection request, precede individual calls to
       XtGetSelectionValue and XtGetSelectionValueIncremental with correspond-
       ing individual calls to XtSetSelectionParameters, and enclose these all
       within XtCreateSelectionRequest and XtSendSelectionRequest.  XtGetSe-
       lectionValues and XtGetSelectionValuesIncremental cannot be used  to
       make selection requests with parameterized targets.
