What this preprocessor does in // this case is replace all the instances of *alloc/free with the expanded // macros - this way we cleverly replace all the calls to the standard C // memory (de)allocation functions. The same is done for new/delete // // Of course, we have the drawback that we can't name a member function of // a class *alloc or free and we can't overload the new/delete operators without // first undefining these macros - ah, a C++ preprocessor with RE replacement, // that would be a dream come true :) // #ifndef OGRE_MEMORY_MACROS #define OGRE_MEMORY_MACROS #if OGRE_DEBUG_MEMORY_MANAGER && OGRE_DEBUG_MODE # define new (::Ogre::MemoryManager::instance().setOwner(__FILE__,__LINE__,__FUNCTION__),false) ?
