关于调试程序的宏问题

struct student{
        struct man man;
        char *id;
        char *major;
        struct teacher *teacher;
};

struct teacher{
        struct man man;
        char *major;
        char *addr;
        struct student *student;
};

struct man{
        int age;
        char *name;
};

void show_student(struct student *student)
{
        show_man(&student->man);
        _show_student(student);
}

void show_teacher(struct teacher *teacher)
{
        show_teacher(&teacher->man);
        _show_teacher(teacher);
}

void show_man(struct man *man)
{
        _show_man(man);
}

char* funcion(struct student *student,struct teacher *teacher)
{
        student->teacher=teacher;
        teacher->student=student;
        return student->major;
}

DECLARE_FUNCTION_TABLE(table)
        FUNCTION_ADD(struct student,show_student);
        FUNCTION_ADD(struct teacher,show_teacher);
        FUNCTION_ADD(struct man    ,show_man        );
END_DECLARE_TABLE

#define debug(func,...) _debug(__FILE__,__FUNCTION__,__LINE__,#func)

int main()
{
        struct student *student=...;//定义一个学生并设置信息
        struct teacher *teacher=...;//定义一个老师并设置信息
//        char *major=function(student,teacher);
        char *major=debug(function,student,teacher);
}

每定义一个类型或函数都将其加入表中.
debug宏通过函数名查表得到函数返回值类型,各参数类型及函数指针,
然后将调用该函数,并打印出实参信息和func返回值信息,每个类型的打印函数可通过查表获得.
这个宏该如何实现呢?

函数的返回值如何打印呢？
