Typical examples of pointers are start pointers, end pointers, and stack pointers. These pointers can either be absolute (the actual physical address or a virtual address in virtual memory ) or relative (an offset from an absolute start address ("base") that typically uses fewer bits than a full address, but will usually require one additional ...
In computing, a pointer or mouse pointer (as part of a personal computer WIMP style of interaction) [10] [11] [12] is a symbol or graphical image on the computer monitor or other display device that echoes movements of the pointing device, commonly a mouse, touchpad, or stylus pen. It signals the point where actions of the user take place.
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.
Examples a computer mouse is an indirect , relative , isotonic , position-control , translational input device with two degrees of freedom (x, y position) and two states (tracking, dragging). a touch screen is a direct , absolute , isometric , position-control input device with two or more degrees of freedom (x, y position and optionally ...
Web browsers are an example of these types of windows. Text terminal windows present a character-based, command-driven text user interfaces within the overall graphical interface. MS-DOS and Unix consoles are examples of these types of windows. Terminal windows often conform to the hotkey and display conventions of CRT-based terminals that ...
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.
In a segmented architecture computer, a far pointer is a pointer to memory in a specific context, [1] such as a segment selector making it possible to point to addresses outside of the default segment. Comparison and arithmetic on far pointers is problematic: there can be several different segment-offset address pairs pointing to one physical ...
Point and click are one of the actions of a computer user moving a pointer to a certain location on a screen (pointing) and then pressing a button on a mouse or other pointing device (click). An example of point and click is in hypermedia, where users click on hyperlinks to navigate from document to document.
