XtOffset(3Xt)              XT FUNCTIONS             XtOffset(3Xt)


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

SYNTAX
       Cardinal XtOffset(pointertype, fieldname)
             Type pointertype;
             Field fieldname;

       Cardinal XtNumber(array)
             ArrayVariable array;

ARGUMENTS
       array     Specifies a fixed-size array.

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

       pointertype
                 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.
