Compiler error C2694'override_function': overriding virtual function has less restrictive exception specification than base class virtual member function 'base_function' Compiler error C2695'override_function':
在基类的构造函数或析构函数中直接或间接的调用纯虚函数举个在基类构造函数中间接调用纯虚函数的例子:class Base { public: Base(){callVirtual();} void callVirtual(){virtualFunc();} virtual void virtualFunc() = 0; }; class Derived: public Base { public: virtual void virtualFunc(){} }; Deriv...
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, a direct or indirect call to an unimplemented pure virtual function from a constructor or destructor results in undefined behavior....
How to call a function in another process (C++) How to call method from another project in native C++ how to call non static member function from Static Function? How to capture file open,close, lock and unlock events in windows OS? how to cast a unique_ptr from base class to derived...
WriteFile( hFileToWrite, pbData, cbData, &dwWrittenBytes, NULL) || (dwWrittenBytes != cbData)) { return FALSE; } return TRUE; } //+--- // Callback function used for decoding streamed Signing. //--- BOOL WINAPI DecodeCallback( const void *pvArg, BYTE *pb...
The simple answer to this first question is that a callback function isa function that is called through a function pointer.If you pass the pointer (address) of a function as an argument to another, when that pointer is used to call the function it points to it is said that a call bac...

注2:一个小小的提醒,第二个“()”是一个运算符,名字叫函数调用运算符(function call operator)。3.指针的算术运算。请再次记住:指针不是一个简单的类型,它是一个和指针所指物的类型复合的类型。因此,它的算术运算与之(指针所指物的类型)密切相关。int a[8];int* p = a;int* q = p + 3;p++;指针...
