Configure Doxygen to ignore the Source-Code Annotation Language (SAL)

Question

I have some classes that are documented with Doxygen. Additionally, they are annotated with Microsoft's Source-Code Annotation Language (SAL) to support static code analysis.

//! The majestic class.
class Foo {
    //! \brief do something
    //! \param [out] pResult The result value is stored here.
    //! \returns The return value Succcess indicates success.
    _Success_(return == Success)
    virtual Result_t DoSomething(_Out_ uint32_t *pResult) = 0;
};

In this case, Doxygen reports a warning:

argument 'pResult' of command @param is not found in the argument list of Foo::_Success_(return==Success)=0

So, Doxygen is confused by the annotation statement _Success_(). How can I hide the return value annotation _Success_(return == Success) to Doxygen without adding clutter to the source file? This does the job, but looks too verbose:

//! The majestic class.
class Foo {
    //! \brief do something
    //! \param [out] pResult The result value is stored here.
    //! \returns The return value Succcess indicates success.
    //! \cond INTERNAL
    _Success_(return == Success)
    //! \endcond
    virtual Result_t DoSomething(_Out_ uint32_t *pResult) = 0;
};

Can this be implemented by configuring Doxygen and leaving the source code untouched?

Answer 1

In the doxygen manual in the chapter Preprocessing there is a part:

A typically example where some help from the preprocessor is needed is when dealing with the language extension from Microsoft: __declspec. The same goes for GNU's __attribute__ extension. Here is an example function.

In your case the following would probably work:

ENABLE_PREPROCESSING = YES
MACRO_EXPANSION = YES
EXPAND_ONLY_PREDEF = YES
PREDEFINED = _Success_(x)=
