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...
although there is no boundaries on defining such functions which act like them. You need to make functions which act like the constructors and destructors and then call them manually.
一、gcc为函数提供了几种类型的属性,其中包含:构造函数(constructors)和析构函数(destructors),可带优先级。 使用类似下面的方式来指定这些属性: static void start(void) __attribute__ ((constructor)); static void stop(void) __attribute__ ((destructor)); 二、带有"构造函数"属性的函数将在main()函数之...

Constructors and destructors also have a slight penalty associated with them. These special methods are guaranteed to be called each time an object of the type is created or goes out of scope, respectively. However, this small amount of overhead is a reasonable price to pay for fewer bugs....
