Constructor & Destructor Documentation
ost::SocketService::SocketService(intpri=0,size_tstack=0,constchar*id=NULL)
Create a service thread for attaching socket ports. The thread begins execution with the first attached
socket.
Parameterspri of this thread to run under.
stack stack size.
id thread ID.
virtualost::SocketService::~SocketService()[virtual]
Terminate the thread pool and eliminate any attached socket ports.
Detailed Description
The SocketService is a thread pool object that is meant to service attached socket ports.
Multiple pool objects may be created and multiple socket ports may be attached to the same thread of
execution. This allows one to balance threads and sockets they service rather than either using a single
thread for all connections or a separate thread for each connection. Features can be added through
supported virtual methods.

Member Function Documentation
intost::SocketService::getCount(void)const[inline]
Get current reference count. This can be used when selecting the least used service handler from a pool.
Returns
count of active ports.
virtualvoidost::SocketService::onCallback(SocketPort*port)[protected],[virtual]
Called for each port that is being processed in response to an event. This can be used to add additional
notification options during callback in combination with update().
ParametersportSocketPort who's callback events are being evaluated.
virtualvoidost::SocketService::onEvent(void)[protected],[virtual]
Called once each time the service thread is rescheduled. This is called after the mutex is locked and can
be used to slip in additional processing.
virtualvoidost::SocketService::onUpdate(unsignedcharbuf)[protected],[virtual]
Handles all requests other than 'termination'.
Parametersbuf request id as posted from update().
voidost::SocketService::update(unsignedcharflag=0xff)
Notify service thread that a port has been added or removed, or a timer changed, so that a new schedule
can be computed for expiring attached ports. A '0' is used to terminate the service thread, and
additional values can be specified which will be 'caught' in the onUpdate() handler.
Parametersflag update flag value.
