An autorelative pointer is a pointer whose value is interpreted as an offset from the address of the pointer itself; thus, if a data structure has an autorelative pointer member that points to some portion of the data structure itself, then the data structure may be relocated in memory without having to update the value of the auto relative ...
A function pointer, also called a subroutine pointer or procedure pointer, is a pointer referencing executable code, rather than data. Dereferencing the function pointer yields the referenced function , which can be invoked and passed arguments just as in a normal function call.
The placement overloads of operator new and operator delete that employ an additional void * parameter are used for default placement, also known as pointer placement. Their definitions by the Standard C++ library, which it is not permitted for a C++ program to replace or override, are: [7] [8] [9]
In the C++ programming language, auto_ptr is an obsolete smart pointer class template that was available in previous versions of the C++ standard library (declared in the <memory> header file), which provides some basic RAII features for C++ raw pointers. It has been replaced by the unique_ptr class.
Smart pointers typically keep track of the memory they point to, and may also be used to manage other resources, such as network connections and file handles. Smart pointers were first popularized in the programming language C++ during the first half of the 1990s as rebuttal to criticisms of C++'s lack of automatic garbage collection. [1] [2]
Yashavant Kanetkar is an Indian computer science author, known for his books on programming languages. He has authored several books on C, C++, VC++, C#, .NET, DirectX and COM programming.
In computer science, pointer analysis, or points-to analysis, is a static code analysis technique that establishes which pointers, ... "Pointer Analysis" (PDF).
When an object is created, a pointer to this table, called the virtual table pointer, vpointer or VPTR, is added as a hidden member of this object. As such, the compiler must also generate "hidden" code in the constructors of each class to initialize a new object's virtual table pointer to the address of its class's virtual method table.
