In its classic form, a callback (aka callback function) is a function that is passed as an argument to another function. The function that accepts the callback as an argument is expected to call back on it (execute it) at a certain point in time.

Callbacks: Callbacks allow you to create flexible and modular functions and enable you to separate hardware and software operations. Since callbacks are software functions, they often define actions in response to an interrupt or another condition, but will not cause a direct change in the flow of the processor.

Mar 7, 2012 · “In computer programming, a callback is a reference to executable code, or a piece of executable code, that is passed as an argument to other code. This allows a lower-level software layer to call a subroutine (or function) defined in a higher-level layer.” - Wikipedia. Callback in C using Function Pointer

May 5, 2009 · In computer programming, a callback is a reference to executable code, or a piece of executable code, that is passed as an argument to other code. This allows a lower-level software layer to call a subroutine (or function) defined in a higher-level layer.

Aug 24, 2014 · In computer programming, a callback is a reference to executable code, or a piece of executable code, that is passed as an argument to other code. This allows a lower-level software layer to call a subroutine (or function) defined in a higher-level layer.

This note describes how the simple idea of function-as-parameter, also known as callback, leads to a number of well-known design patterns. In par-ticular, the following design patterns appear: Strategy, Adapter, Composite, Decorator, and Observer. Conciseness of …

Callbacks allow you to create more flexible and modular functions and enable you to separate hardware and software operations. They also allow for multiple programmers to work on a project and provide code to be combined with the main application program.

Sep 14, 2018 · In computer programming, a callback is executable code that is passed as an argument to other code. It allows a lower-level software layer to call a subroutine (or function) defined in a higher-level layer.

In computer programming, a callback is a function that is stored as data (a reference) and designed to be called by another function – often back to the original abstraction layer. A function that accepts a callback parameter may be designed to call back before returning to its caller which is known as synchronous or blocking .
