A void function does not return any value as output and can take input values. The function below seems a void function, but there is the operator *, why?
void *function(){
printf("hello")
}

You'll need to study _pointers_ in your beginner-level C programming book. The `*` here is not an operator but part of the return type declaration. – Lundin May 19 '20 at 09:21

@Lundin in the C course i studied only void function and void pointer like void *p, but i have never seen void *function. – Federica Guidotti May 19 '20 at 09:24

It is a function returning a `void *`, simple as that. – Lundin May 19 '20 at 09:25

That is not a void function. That is a function that returns a void* (pointer). But it seems incomplete, because the printf() has no semicolon ; and the function does not actually return a void*.

can you write an example to understand how to use it please? – Federica Guidotti May 19 '20 at 09:39

You have to study the pointers chapters. If you have a C book, it has to have a chapter about it. If not, just google it, this topic is far too complex to explain in a SO answer. – DarkAtom May 19 '20 at 09:41
