43. Callback Function : C

Callback Function

What is a Callback Function?

• In case a capacity's reference is passed to one more capacity as a contention to call it, it will be known as a Callback work. 
• This permits the developer to compose less code and accomplish more things. A callback work is a capacity that is called by utilizing a capacity pointer. 
• Capacity Pointer, as its name recommends, is a pointer to a capacity. 

The distinction between Function Pointer and Callback Functions - 

• A capacity pointer is a pointer that focuses on capacity. While, callback capacities are work pointers passed as boundaries of the capacity, which can be called back when an occasion happens. 
• A capacity pointer is a location of the capacity. While, callback capacities pass work pointer as a contention, and the guest would callback if something occurs.
