A client session with a Sametime server is encapsulated in the mwSession structure.
The session controls channels, provides encryption ciphers, and manages services using messages over the Master channel.
A session does not directly communicate with a socket or stream, instead the session is initialized from client code with an instance of a mwSessionHandler structure. This session handler provides functions as call-backs for common session events, and provides functions for writing-to and closing the connection to the server.
A session does not perform reads on a socket directly. Instead, it must be fed from an outside source via the mwSession_recv function. The session will buffer and merge data passed to this function to build complete protocol messages, and will act upon each complete message accordingly.

enum mwSessionState |
adds a cipher to the session.
adds a service to the session.
If the session is started (or when the session is successfully started) and the service has a start function, the session will request service availability from the server. On receipt of the service availability notification, the session will call the service's start function.
int mwSession_forceLogin | ( | struct mwSession * | s | ) |
respond to a login redirect message by forcing the login sequence to continue through the immediate server.
void mwSession_free | ( | struct mwSession * | ) |
stop, clear, free a session.
Does not free contained ciphers or services, these must be taken care of explicitly.
struct mwChannelSet* mwSession_getChannels | ( | struct mwSession * | ) | [read] |
find a cipher by its type identifier
GList* mwSession_getCiphers | ( | struct mwSession * | ) |
a GList of ciphers in this session.
The GList needs to be freed after use
gpointer mwSession_getClientData | ( | struct mwSession * | session | ) |
struct mwSessionHandler* mwSession_getHandler | ( | struct mwSession * | ) | [read] |
obtain a reference to the session's handler

obtain the value of a previously set property, or NULL
find a service by its type identifier
GList* mwSession_getServices | ( | struct mwSession * | ) |
a GList of services in this session.
The GList needs to be freed after use
enum mwSessionState mwSession_getState | ( | struct mwSession * | ) |
current status of the session
gpointer mwSession_getStateInfo | ( | struct mwSession * | ) |
additional status-specific information.
Depending on the state of the session, this value has different meaning.

int mwSession_sendAnnounce | ( | struct mwSession * | s, |
gboolean | may_reply, | ||
const char * | text, | ||
const GList * | recipients | ||

) |
instruct a STARTED session to check the server for the presense of a given service.
The service will be automatically started upon receipt of an affirmative reply from the server. This function is automatically called upon all services in a session when the session is fully STARTED.
Services which terminate due to an error may call this on themselves to re-initialize when their server-side counterpart is made available again.
