11.1.2 Connection Handles

Connection handles maintain connection information. They can be used to open or close connections. For example, when a connection is established, the connection handle retains the host information of the connection destination (host name and port number). And because it is possible to create multiple connection handles with a single process, connection handles can also be used in multi-thread environments.

Connection handles can be used to perform the following operations.
