Session status.
|
|
|
|
|
|
Close a session without any further communication. Can be used to abort a connection if
This method is void, because it *must* complete, no matter which errors it encounters. Furthermore, it is primarily intended to be called from destructors which are also void. Consider it to be an extended desctrutor. |

|
Close a channel. This is a very partial implementation of RFC 3080. For syslog-raw, I honestly and strongly beliefe it works. However, there may be implementations of syslog raw where it will not work or at least not work fully correctly.
|
|
|
Closes the BEEP session. First, the management channel (channel 0) is taken down and then the TCP stream is closed. This function can only be called after all sessions have been closed. Once the function returns, the session object is no longer valid and can no longer be used. |
|
|
Destructor. pThis is invalid when this function returns. The caller can no longer use it. The caller is also not allowed to free it - this is already done in this method. |
|

|
Receive frames off the tcp stream. SEQ frames are processed as they arrive. Other frames are buffered in the respective in-memory queue. This is a helper to sbSessRecvFram() and sbSessSendFram().
|
|
|
Open a BEEP channel on an established session.
|
|
||||||||||||||||
|
Open a BEEP session. The initial greeting is sent and the remote peers initial greeting is accepted. Channel 0 is initialized and brought into operation.
|
|
||||||||||||
|
Process the remote peer's greeting message. Most importantly, the list of profiles is extracted and stored in the session object.
|
|
||||||||||||
|
Receive a frame for a specified channel from the tcp stream. This method handles intermixed frames from other channels. It calls back into the frame object to do the actual frame read (if no frame is buffered). See architecture::c for a full description.
|
|
||||||||||||||||
|
Open a BEEP session. This method is called if a REMOTE peer requests an session open. As such, it does only the most pressing initialization work and then returns back to the caller. |
|
||||||||||||
|
Retrieve the channel object associated with the channel number. This method allows to retrieve a channel number based on the actual channel.
|
|
||||||||||||||||
|
Send the provided frame on the provided channel. While sending, concurrently incoming frames are buffered and SEQ frames are processed. This method blocks until pFram could be sent (this means it may need to wait for the proper SEQ frame). See architecture::c for full details on how this method "drives the BEEP stack".

|
Send a greeting message based on the currently registered profiles. We generate the greeting via a simple stringbuf, not with an XML parser. This saves execution time and is as good as the XML thing...
