XtOffset(3Xt)                        SysV                        XtOffset(3Xt)



NAME
     XtOffset, XtNumber - determine the byte offset or number of 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 the
               structure.

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.
