C function that returns a pointer to an array correct syntax?

In C you can declare a variable that points to an array like this:

int int_arr[4] = {1,2,3,4};
int (*ptr_to_arr)[4] = &int_arr;

Although practically it is the same as just declaring a pointer to int:

int *ptr_to_arr2 = int_arr;

But syntactically it is something different.

Now, how would a function look like, that returns such a pointer to an array (of int e.g.) ?

>Solution :

A declaration of int is int foo;.

A declaration of an array of 4 int is int foo[4];.

A declaration of a pointer to an array of 4 int is int (*foo)[4];.

A declaration of a function returning a pointer to an array of 4 int is int (*foo())[4];. The () may be filled in with parameter declarations.
