Event Channel APIs

Once the socket connection has been established, the EIO API is used to provide the high level calls to pass events to and from the socket: EIO_stackInit initialises the event stack. EIO_open initialises the event I/O connection EIO_registerReceiveFn registers a callback function for receiving events. EIO_addFilter specifies which event variants to receive EIO_removeFilter removes an event variant filter EIO_sendEvent sends an event to the engine. EIO_stackReset reset the event stack. EIO_close deallocates resources used by the EIO connection.
