72 In the case of a read call, you should pass an *initialized* buffer which will
73 be filled with data before the read callback is triggered. The ``uv_fs_*``
87 simply drives the next read. Thus read and write proceed in lockstep via
121 same patterns as the read/write/open calls, returning the result in the
