Artifact b2b7b98b3920d1e98eaec90c559c2d20221c1ee47d2b9f3f69e3de25ca07ec0d:

• File src/exceptions/OFListenFailedException.m — part of check-in [8d2a5052fd] at 2014-01-25 17:39:13 on branch trunk — Generalize stream / socket related exceptions

  This is in preparation for adding UDP sockets, as UDP sockets and TCP
  sockets have no common superclass, as one is stream-oriented while the
  other is packet-oriented.

  Read and write exceptions are for any object now, as they are useful for
  a lot more than just for streams, while the others (bind, listen, etc.)
  are for any socket now (the type is id in this case, though, as there is
  no common superclass). (user: js, size: 1532) [annotate] [blame] [check-ins using]
