It should work, really. The problem is that you passed a user
defined type to fwrite() where it expected a pointer.
You should have sizeof(User) as the second parameter,
though, and use the address of ToAdd.
fwrite(&ToAdd, sizeof(User), 1, stream);
Now ToAdd is a given as an address, rather than a defined
type. fwrite() wants a pointer to work with.
