Open and possibly create a file (extended)
§Example
use core::mem::size_of;
let path = "/etc/passwd";
let mut how = nc::open_how_t{
flags: nc::O_RDONLY as u64,
..nc::open_how_t::default()
};
let how_size = size_of::<nc::open_how_t>();
let ret = unsafe { nc::openat2(nc::AT_FDCWD, path, &mut how, how_size) };
assert!(ret.is_ok());
let fd = ret.unwrap();
let ret = unsafe { nc::close(fd) };
assert!(ret.is_ok());
