dereference简单来说,就是根据reference取得资源。 这个词,在C/C++中较常见,*pointer操作,就叫做dereference,即取回指针所指的值。 wikipedia的词条上是这样写的:Accessing the value referred to by a reference is called dereferencing it. 本身dereference在

I need to pass a pointer to a two-dimensional array to a C/C++ dll. I want to dereference a pointer to a two-dimensional array from a C/C++ dll.
Smart pointers are C++ objects that wrap raw pointers and provide additional features such as automatic memory management, reference counting, and ownership semantics. When a smart pointer is constructed, it takes ownership of the raw pointer and ensures that the memory is properly deallocated when ...
int& r = i声明一个整型的reference,并将其初始化为引用i。 C++专用。请注意,引用必须在初始化时分配,因此不可能使用int& r;。 类似地: void foo(int i)声明一个函数,接受一个整数(按值传递,即作为副本)。 void foo(int* p)声明一个函数,接受一个指向整型的指针。 void foo(int& r)声明一个函数,接...
The driver that imports the interface is responsible for calling the InterfaceDereference routine to decrement the reference count after the driver is no longer using the interface. For example, a driver that requests a pointer to the interface by sending an IRP_MN_QUERY_INTERFACE request calls ...
