32 /**
33 * Sets up the connection ID to connect to the remote host.
34 *
35 * For the connection-oriented client (TCP), it prepares a connection from the local
36 * to the peer system. The connection oriented client does not need
37 * to call rnet_bind() before rnet_connect(), since rnet_connect() would automatically
38 * use the local address of the client and allocate dynamically a free local port.
39 *
40 * rnet_connect() returns immediately, does not wait for the connection to be properly setup.
41 * The RNET_CONNECT_CFM message is sent when the connection is established.
42 * If the connection could not be properly established, a RNET_ERROR_IND
43 * message is sent.
44 *
45 * A connectionless client (UDP) would use rnet_connect() to locally specify
46 * the remote server, but no connection is open. But the remote address
47 * is then known and does not need to be specified again.
48 * rnet_connect() takes as parameter a fully initialized address structure,
49 * specifying server address and port.
50 *
51 * @param desc Connection identifier [IN].
52 * @param peer_addr Peer address [IN].
53 * @param peer_port Peer port [IN].
54 * @return RNET_MEMORY_ERR No buffer space available.
55 * RNET_NOT_INITIALIZED NET subsystem not initialized (internal error).
56 * RNET_INTERNAL_ERR Network subsystem failed.
57 * or Attempt to connect forcefully rejected.
58 * or Attempt to connect datagram socket to broadcast address
59 * RNET_INVALID_PARAMETER Invalid connection ID.
60 * or Remote address not a valid address (such as ADDR_ANY).
61 * RNET_NOT_SUPPORTED Addresses in the specified family cannot be used with this socket.
62 * RNET_IN_USE Already connected (connection-oriented only).
63 * RNET_NET_UNREACHABLE The network cannot be reached from this host at this time.
64 * RNET_TIMEOUT Attempt to connect timed out without establishing a connection.
65 * RNET_NOT_READY Still processing a callback function.
66 * RNET_OK Connection in progress
67 * RNET_CONNECT_CFM will be sent when the connection
68 * has been successfully completed.
