| int(*)(void *data, struct pw_impl_port *port) | callback, | ||

Iterate the ports in the given direction.
The callback should return 0 to fetch the next item, any other value stops the iteration and returns the value. When all callbacks return 0, this function returns 0 when all items are iterated.
