早期版本的编译器允许派生类调用间接派生 private virtual 基类的成员函数。 这种旧行为不正确,也不符合 C++ 标准。 编译器不再接受这种方式编写的代码,因此会发出编译器错误 C2280。 Output 复制 error C2280: 'void *S3::__delDtor(unsigned int)': attempting to reference a deleted function 示例(之前)...

MFC DAO objects created in this way use DAO's default workspace, which is created once and reused. To release a workspace and its contained objects, call the workspace object's Close member function. CDaoWorkspace::Close Call this member function to close the workspace object. Copy virtual ...
In general, when an object has a virtual function table (a vtable) in it, dbx can use the information in the vtable to correctly determine an object's type. You can use the print or display command with the -r (recursive) option. dbx displays all the data members directly defined by ...

-xdebugformat=dwarf generates debugging information using the dwarf standard format (default). If you do not specify -xdebugformat, the compiler assumes -xdebugformat=dwarf. This option requires an argument. This option affects the format of the data that is recorded with the -g option. Some sm...
