Copy-on-write (COW), also called implicit sharing [1] or shadowing, [2] is a resource-management technique [3] used in programming to manage shared data efficiently. Instead of copying data right away when multiple programs use it, the same data is shared between programs until one tries to modify it.
Though std::string no longer uses it, many (perhaps most) alternative string libraries still implement copy-on-write strings. Some string implementations store 16-bit or 32-bit code points instead of bytes, this was intended to facilitate processing of Unicode text. [5]
C++/WinRT is an entirely standard modern C++17 language projection for Windows Runtime (WinRT) APIs, implemented as a header-file-based library, and designed to provide first-class access to the modern Windows API. With C++/WinRT, Windows Runtime APIs can be authored and consumed using any standards-compliant C++17 compiler.
The length of a string is the number of code units before the zero code unit. [1] The memory occupied by a string is always one more code unit than the length, as space is needed to store the zero terminator. Generally, the term string means a string where the code unit is of type char, which is exactly 8 bits on all modern machines.
When 010 Editor executes a Binary Template on a binary data file, each variable defined in the Binary Template is mapped to a set of bytes in the binary file and added to a hierarchical tree structure. The tree structure can then be used to view and edit data in the binary file in an easier fashion than using the raw hex bytes.
In computer programming, a rope, or cord, is a data structure composed of smaller strings that is used to efficiently store and manipulate longer strings or entire texts. For example, a text editing program may use a rope to represent the text being edited, so that operations such as insertion, deletion, and random access can be done ...
Pinning an AOL app to your Windows 10 Start menu is a simple task, follow the steps below. Open the Windows Start menu and click All apps. Locate the AOL app in the list. Right-click on the app name. A small menu will appear. Click Pin to Start to add this app to your Start menu.
In DOS and Windows (and in CP/M and many DEC operating systems such as the PDP-6 monitor, [3] RT-11, VMS or TOPS-10 [4]), reading from the terminal will never produce an EOF. Instead, programs recognize that the source is a terminal (or other "character device") and interpret a given reserved character or sequence as an end-of-file indicator ...
