XtOffset(3Xt)                                       XtOffset(3Xt)



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

SYNOPSIS
     Cardinal XtOffset(pointer-type, member-name)
     Type pointer-type;
     Field member-name;

     Cardinal XtNumber(array)
     ArrayVariable array;

DESCRIPTION
     The XtOffset macro is usually used to determine the offset
     of various resource members 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.

   Arguments
     These macros accept the following arguments:

     array   Specifies a fixed-size array.

     member-name
             Specifies the name of the member for which to calcu-
             late the byte offset.

     pointer-type
             Specifies a type that is declared as a pointer to
             the structure.
