Passing pointers to functions

Passing pointers to functions: C: Data Structures, Pointers, and File Systems
Passing pointers to functions: C: Data Structures, Pointers, and File Systems

When a function requires a pointer as an argument, what it really needs is an address. To pass a pointer to a function, you can use a pointer variable or use the ampersand operator to pass the address of any variable. Within the function, a pointer, or address, passed is treated as a pointer: it's a memory location or, with the asterisk operator, it's the value at that location. By passing pointers to a function, your code can manipulate values directly without having to return them.
