setcallback

SetCallback is a function or method commonly found in programming environments that allows a user to define a specific piece of code, known as a callback function, to be executed when a particular event occurs or a certain condition is met. This is a fundamental concept in event-driven programming and asynchronous operations.

The primary purpose of SetCallback is to decouple the execution of code from the direct flow of control. Instead of a program waiting for an action to complete, it can register a callback function to handle the result or notification when that action is finished. This is particularly useful for operations that might take time, such as network requests, file I/O, or user interactions.

When SetCallback is invoked, it typically takes two arguments: the event or condition to listen for, and the callback function itself. Once registered, the system monitors for the specified event. Upon detection, the associated callback function is automatically executed. The callback function can then perform any necessary actions, such as updating the user interface, processing data, or triggering further operations. This pattern promotes modularity and responsiveness in software design.
