Among such attributes the below function attributes are used to define constructors and destructors in C language. These would only work under GCC. As there is no objects and class approach in C the working of
Constructors and Destructors are special functions. These are one of the features provided by an Object Oriented Programming language. Constructors and Destructors are defined inside an object class. When an object is instantiated, ie. defined of or dynamically allocated of that class type, the Con...

If you add parameter data members (which you must do manually) you must also manually add an initialization in the class constructor to reflect the number of parameters (which must be at least as large as the number of '' placeholders in your m_strFilter or m_strSort string). The ...
To establish a Notificable thread a developer has to add the SUPPORT_THREAD_NOTIFICATION macro in his CThread-Derived class constructor where the thread-task handler (the virtual ThreadHandler() method) is actually implemented. He also has to implement the thread-task handler following the specific...

C.82: Don't call virtual functions in constructors and destructors C.82:不要在构造函数或析构函数中调用虚函数 Reason(原因) The function called will be that of the object constructed so far, rather than a possibly overriding function in a derived class. This can be most confusing. Worse, ...
