Yes, * defines a pointer. The &, in a C++ function declaration, means
pass by reference. So,
func(int*&foo) {
foo = new int;
}
means a function that accepts pointer to int using pass by reference
semantics.
If you do
int* myptr;
func(myptr);
myptr will be changed after func exits. In C, you would do
func(int** foo) {
*foo = malloc(sizeof(int));
}
int* myptr
func(&myptr);
You should get a good c++ book, which explains this syntax in more detail.
