Function flistxattr 

pub fn flistxattr<Fd: AsFd, Buf: Buffer<u8>>(
    fd: Fd,
    list: Buf,
) -> Result<Buf::Output>

flistxattr(fd, list.as_ptr(), list.len())—List extended filesystem attributes on an open file descriptor.

Unlike the libc flistxattr function, this function does not treat an buffer with zero length as a way to return the size of the attribute. To obtain the size, use flistxattr_query.
