Imagine some kind of game engine class which has a function that is fired, each time the users presses a button on his keyboard and a set of functions that control your game behaviour. With callbacks you can (re
A callback is a function (i.e., subroutine in the code) passed to other functions as an argument to be called later in program execution. Callback functions can be implemented using different language-specific tools, but in C++, all of them are known as callable objects. Callable objects ...

Callback functions form the basis for many types of event driven programming. Events like on_click are really callback routines.Perhaps you've done callback routines in other languages. What a syntactic mess! Here's a C example:Calling function definition int binary_op(int a, int b, int ...

Due to its complex syntax of the nested callback, its also called the callback hell. Whenever you need to use the nested callback functions, you can use the promises or async/await to write the simpler code. In the upcoming chapters, you will learn the promises and async/await to handle...
Callbacksin C are important functions that help users in creating programs with more complex behavior. By allowing the lower-level functions to be called when needed,callbacksenable the program to break down complex behavior into small, reusable pieces. This makes it simpler to maintain and trouble...
If functions are a result of another “factory” function, then the factory function must be defined outside pipeline definition function and decorated with<nvidia.dali.pipeline.do_not_convert>. More details can be found in<nvidia.dali.pipeline.do_not_convert>documentation. ...
