Writing

Resulting stream

Create a stream from a "receive" and "send" action. The following properties apply:

  • Regardless of the provided "receive" and "send" functions, reading and writing from the stream will be thread-safe, i.e. this function will create a receive and write lock to be used internally.
  • Reading from or writing or to a closed Stream will always throw an exception, even if the underlying "receive" and "send" functions do not (we do the bookkeeping).
  • Streams should always be closed.
