requirements. At the time the function prototypes were introduced in ANSI C, the func-

tions exposed by this ﬂag were only deﬁned in SVID3.

_CLASSIC_TYPES

The _CLASSIC_TYPES

macro can be deﬁned by the programmer to obtain pre-7.0 style

function return types and structure element types. This macro has been provided only as a

transition aid when migrating from the pre-7.0 version of HP-UX to standards-based HP-

UX. Use of this macro is strongly discouraged as this functionality will be removed in a

future release of HP-UX. Note that no function prototypes are provided when using this

feature test macro.
