- // CSecurity - class on the client side for handling security handshaking. A
- // derived class for a particular security type overrides the processMsg()
- // method. processMsg() is called first when the security type has been
- // decided on, and will keep being called whenever there is data to read from
- // the server until either it returns 0, indicating authentication/security
- // failure, or it returns 1, to indicate success. A return value of 2
- // (actually anything other than 0 or 1) indicates that it should be called
- // back when there is more data to read.
- //
- // Note that the first time processMsg() is called, there is no guarantee that
- // there is any data to read from the CConnection's InStream, but subsequent
- // calls guarantee there is at least one byte which can be read without
- // blocking.
