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