[Doxygen-users] EXPAND_AS_DEFINED and Poor Mans Inheritance

[Peter S. <pet...@hu...>]

Hello all

I one project, I'm forced to use C. I try to get some struct reuse and
sort of object inheritance with the following contruct:

//------ begin of example

#define BASECLASS \
    int         aMember;        /**< Members Doc */ \
    /* END OF BASECLASS */

/**
 * This is the base class
 */
typedef struct BaseClass {
    BASECLASS
} BaseClass;

/**
 * This is a derived class
 */
typedef struct DerivedClass {
    BASECLASS
    int         additionalMember;   /**< also documented */
} DerivedClass;

//------ end of example

To get the documentation right, I'm using the MACRO_EXPANSION,
EXPAND_ONLY_PREDEF and EXPAND_AS_DEFINED = BASECLASS macros. But that
works only halfway: the 'aMember' appears in the documentation if
HIDE_UNDOC_MEMBERS is not set, but without documentation.

It seems that the doxygen comments inside my macro BASECLASS are
swallowed during the preprocessing stage. I'd like to happen the macro
expansion first and then the extraction of the comments...

Is there a way to make this work?

Regards, Peter
