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 It has been replaced by the unique_ptr class.
In C++, a smart pointer is implemented as a template class that mimics, by means of operator overloading, the behaviors of a traditional (raw) pointer, (e.g. dereferencing, assignment) while providing additional memory management features. Smart pointers can facilitate intentional programming by expressing, in the type, how the memory of the ...
In computer science, a tagged pointer is a pointer (concretely a memory address) with additional data associated with it, such as an indirection bit or reference count.This additional data is often "folded" into the pointer, meaning stored inline in the data representing the address, taking advantage of certain properties of memory addressing.
A pointer a pointing to the memory address associated with a variable b, i.e., a contains the memory address 1008 of the variable b.In this diagram, the computing architecture uses the same address space and data primitive for both pointers and non-pointers; this need not be the case.
This diagram represents five contiguous memory regions which each hold a pointer and a data block. The List Head points to the 2nd element, which points to the 5th, which points to the 3rd, thereby forming a linked list of available memory regions. A free list (or freelist) is a data structure used in a scheme for dynamic memory allocation.
The use of pointers may or may not be a requirement, because managed C++ has both value types (__value struct and __value class) and reference types (__gc struct and __gc class). Managed C++ fully support ASP.NET web applications, even though the development is more difficult than with other .NET languages, including some other third party ...
In computer science, pointer swizzling is the conversion of references based on name or position into direct pointer references (memory addresses). It is typically performed during deserialization or loading of a relocatable object from a disk file, such as an executable file or pointer-based data structure .
In MC++, there were two different types of pointers: __nogc pointers were normal C++ pointers, while __gc pointers worked on .NET reference types. In C++/CLI, however, the only type of pointer is the normal C++ pointer, while the .NET reference types are accessed through a "handle", with the new syntax ClassName ^ (instead of ClassName *). This ...
