C | Function pointer and callback function simulation implementation commission and reflection2021-11-28 12:03:42 26 ℃
The function is the core concept of the C language. The main adjustment function (Callee) is a general call relationship. If the modular parameter contains a function pointer, the function pointer can also form a multi-layer call relationship to form a third-party function. Professional terms are called callbacks, and third-party functions called by function pointer parameters are called callback functions. The callback can make the code (herein refer to a function of function pointer to function parameters) more generalized or abstracted, simulating the delegation and reflection grammar of other programming languages.
// C language Simulates the pointer function that needs to be used. The purpose of the function address is achieved by receiving a function address with a pointer function as an address to achieve a method of entrusting other functions. #include
