I know these kind of questions are quite frequent,but still I have some doubts...

From main() I create a struct variable and I pass his address(&) to a function
(this function has a pointer type argument).
Now how can I pass, from this function, the pointer to the struct variable I created from main()?

f(*struct);

f2(*struct);


main()

{

  struct a;


  f(&a);

}


f(*struct a)

{

  f2(what should I write here to pass the pointer?)

}

Should I use a pointer to pointer?
Pointer to pointer are quite confusing can I have some examples or some tutorials?
Thanks in advance.

Sorry I forgot names for arguments

Should I write f2(a)?
