| 4 | // MacAsyncSocket is a kind of AsyncSocket. It only creates sockets |
| 5 | // of the TCP type, and does not (yet) support listen and accept. It works |
| 6 | // asynchronously, which means that users of this socket should connect to |
| 7 | // the various events declared in asyncsocket.h to receive notifications about |
| 8 | // this socket. |
