       array elements

  SYNTAX
       Cardinal XtOffset(pointer_type, field_name)
             Type pointer_type;
             Field field_name;

       Cardinal XtNumber(array)
             ArrayVariable array;

  ARGUMENTS
       array     Specifies a fixed-size array.

       field_name
                 Specifies the name of the field for which to
                 calculate the byte offset.

       pointer_type
                 Specifies a type that is declared as a pointer to

  DESCRIPTION
       The XtOffset macro is usually used to determine the offset
       of various resource fields from the beginning of a widget
       and can be used at compile time in static initializations.

       The XtNumber macro returns the number of elements in the
       specified argument lists, resources lists, and other counted
       arrays.
