Function twz_rt_fd_enumerate_names

pub unsafe extern "C-unwind" fn twz_rt_fd_enumerate_names(
    fd: descriptor,
    buf: *mut name_entry,
    len: usize,
    off: usize,
) -> io_result

Enumerate sub-names in an fd (e.g. directory entries). The buf and len arguments form a &mut name_entry slice, and the off argument specifies how many names to skip for this read. The return value is the number of entries read, or 0 if at end of list.
