# Class SSL.sslfile

Description

  Interface similar to Stdio.File .

  - Handles blocking and nonblocking mode.

  - Handles callback mode in an arbitrary backend (also in blocking mode).

  - Read and write operations might each do both reading and writing. In callback mode that means that installing either a read or a write callback might install both internally. It also means that reading in one thread while writing in another doesn't work.

  - Callback changing operations like set_blocking and set_nonblocking aren't atomic.

  - Apart from the above, thread safety/atomicity characteristics are retained.

  - Blocking characterstics are retained for all functions.

  - is_open , connection init (create ) and close (close ) can do both reading and writing.

  - destroy attempts to close the stream properly by sending the close packet, but since it can't do blocking I/O it's not certain that it will succeed. The stream should therefore always be closed with an explicit close call.

  - Abrupt remote close without the proper handshake gets the errno System.EPIPE .

  - Objects do not contain cyclic references, so they are closed and destructed timely when dropped.
