### camel_tcp_stream_connect ()

    gint                camel_tcp_stream_connect            (CamelTcpStream *stream,
                                                             struct addrinfo *host);

Create a socket and connect based upon the data provided.

`stream` : | a CamelTcpStream object
`host` : | a linked list of addrinfo structures to try to connect, in the order of most likely to least likely to work.
Returns : | `0` on success or `-1` on fail

### camel_tcp_stream_getsockopt ()

    gint                camel_tcp_stream_getsockopt         (CamelTcpStream *stream,
                                                             CamelSockOptData *data);

Get the socket options set on the stream and populate `data`.

`stream` : | a CamelTcpStream object
`data` : | socket option data
Returns : | `0` on success or `-1` on fail

### camel_tcp_stream_setsockopt ()

    gint                camel_tcp_stream_setsockopt         (CamelTcpStream *stream,
                                                             const CamelSockOptData *data);

Set the socket options contained in `data` on the stream.

`stream` : | a CamelTcpStream object
`data` : | socket option data
Returns : | `0` on success or `-1` on fail

### camel_tcp_stream_get_local_address ()

    struct sockaddr *   camel_tcp_stream_get_local_address  (CamelTcpStream *stream,
                                                             socklen_t *len);

Get the local address of `stream`.

`stream` : | a CamelTcpStream object
`len` : | pointer to address length which must be supplied
Returns : | the stream's local address (which must be freed with g_free) if the stream is connected, or `NULL` if not

### camel_tcp_stream_get_remote_address ()

    struct sockaddr *   camel_tcp_stream_get_remote_address (CamelTcpStream *stream,
                                                             socklen_t *len);

Get the remote address of `stream`.

`stream` : | a CamelTcpStream object
`len` : | pointer to address length, which must be supplied
Returns : | the stream's remote address (which must be freed with g_free) if the stream is connected, or `NULL` if not.
