In this example, foo is a pointer to a function taking one argument, an integer, and that returns void. It's as if you're declaring a function called "*foo", which takes an int and returns void; now, if *foo is a function, then foo must be a pointer to a function. (Similarly...

Here s is a pointer to a function sum. Now sum can be called using function pointer s along with providing the required argument values.s (10, 20); CopyExample of Pointer to Function in C#include <stdio.h> int sum(int x, int y) { return x+y; } int main( ) { int (*fp)(...
In C programming language, we can have a concept of Pointer to a function known as function pointer in C. In this tutorial, we will learn how to declare a function pointer and how to call a function using this pointer. To understand this concept, you sho
In wrapper function method: we use an additional wrapper function which takes an additional input as the selection of the callback function to be passed to the target function In TestStand storing the callback function: we create an object reference (to store funciton pointer) in TS, and add...
Here, we will learn how to pass a string (character pointer) in a function, where function argument is void pointer.Consider the given example#include <stdio.h> //function prototype void printString(void *ptr); int main() { char *str="Hi, there!"; printString(str); return 0; } /...
