Returns: i32

argv function
fn() -> *(*(u8))

Get the raw argv pointer (*(*(u8))).

Returns: *(*(u8))

args function
fn() -> ArrayList(String)

Get command-line arguments as an ArrayList(String). The first element is the program name.

Returns: ArrayList(String)

cwd function
fn() -> Result(Path, String)

Get the current working directory as a Path. Returns Err with a message on failure.

Returns: Result(Path, String)

chdir function
fn(path : Path) -> Result(unit, String)
