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

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.
