Freeing a Connection Object

The connection manager can close a connection at any time. The connection manager cannot free the connection object while references to the connection object exist. To free a connection object that has existing references, the connection manager calls the sip_conn_destroyed() function. The library provides this function. When the connection manager invokes the sip_conn_destroyed() function, the stack locates and terminates the transactions that are caching the connection object. The stack frees any resources that had been allocated for TCP handling after terminating the transactions.
