NAME
     XtOffset, XtNumber - determine the byte offset or number of
     array elements

SYNOPSIS
     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.
