LEGACY

#define LEGACY

(

CL

)

( CL < 100 && LIBZYPP_VERSION_MAJOR <= CL ) || ( CL < 10000 && LIBZYPP_SOVERSION <= CL ) || LIBZYPP_VERSION <= CL

Legacy code we still support.

Deprecated items we can't drop immediately because YAST/PK still refer to them or they break binary compatibility, should be enclosed in #if LEGACY(#) where # is either a minor number(<=99), a soversion [<=9999] or numversion [<=999999].

ZYPP_DEPRECATED

#define ZYPP_DEPRECATED

The ZYPP_DEPRECATED macro can be used to trigger compile-time warnings with gcc >= 3.2 when deprecated functions are used.

For non-inline functions, the macro is used at the very end of the function declaration, right before the semicolon, unless it's pure virtual:

int deprecatedFunc() const ZYPP_DEPRECATED; virtual int deprecatedPureVirtualFunc() const ZYPP_DEPRECATED = 0;

Functions which are implemented inline are handled differently: the ZYPP_DEPRECATED macro is used at the front, right before the return type, but after "static" or "virtual":

ZYPP_DEPRECATED void deprecatedFuncA() { .. } virtual ZYPP_DEPRECATED int deprecatedFuncB() { .. } static ZYPP_DEPRECATED bool deprecatedFuncC() { .. }

You can also mark whole structs or classes as deprecated, by inserting the ZYPP_DEPRECATED macro after the struct/class keyword, but before the name of the struct/class:

class ZYPP_DEPRECATED DeprecatedClass { }; struct ZYPP_DEPRECATED DeprecatedStruct { };

However, deprecating a struct/class doesn't create a warning for gcc versions <= 3.3 (haven't tried 3.4 yet). If you want to deprecate a class, also deprecate all member functions as well (which will cause warnings).
