NAME

VistaIOOffset, VistaIOOffsetOf - determine the byte offset of a structure field

SYNTAX

#include <vistaio.h>

size_t VistaIOOffset ( pointer_type , field_name )

Type pointer_type ;
Field field_name ;

size_t VistaIOOffsetOf ( struct_type , field_name )

Type struct_type ;
Field field_name ;

ARGUMENTS

field_name

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

pointer_type

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

struct_type

Specifies a type that is declared as a structure.

DESCRIPTION

The VistaIOOffset and VistaIOOffsetOf macros return the byte offset of the field_name field within its structure.

SEE ALSO

NOTES

These are equivalent to the X Toolkit macros XtOffset (3Xt) and XtOffsetOf (3Xt). ANSI C defines an offsetof macro, which is to be preferred over any of these.
