Opening URLs happens through the `OPEN` system call. `OPEN` takes a C-like, null-terminating string, and two pointer-sized integers, keeping the open flags and the file mode, respectively.
The path argument of `OPEN` do not have to be an URL. For compatibility reasons, it will default to the `file:` scheme. If otherwise specified, the scheme will be resolved by the registrar (see 'The root scheme'), and then opened.
