What is call back in the talk show?

Calling back on the talk show is to recycle the signal.

As a term in talk show, it is an echo of some things mentioned above, and the topic forms a closed loop. In general variety shows, cue is called callback, and callback refers to callback function, or simply callback (callback means that callback will return to the main function after being called by the main function), which refers to a reference of an executable code that passes the function to other codes through parameters.

Callbacks are widely used. For example, suppose there is a function that reads the configuration file and sets the corresponding options according to the contents of the file. Another purpose of callback is to process signals and so on. For example, a POSIX program may not want to terminate immediately upon receiving a SIGTM signal. In order to ensure that everything works well, the program can register the cleaning function as a callback corresponding to the SIGTM signal.

Talk show skills

Callbacks can also be used to control whether a function acts as: Xlib allows the use of custom predicates to determine whether a program should handle a specific event. There are two types of callbacks that control data flow in different ways at runtime: blocking callbacks (also known as synchronous callbacks or only callbacks) and delayed callbacks (also known as asynchronous callbacks).

On the surface, call back means to call back, but when used in a talk show, the meaning changes. Callback actually refers to deduction, which is a skill of talk show. Many people will use this technique when performing talk shows. Tell a joke first, and then repeat part of it in a few minutes. Not simply repeating, but making your repetition more interesting.
