+/**
+ Connect to a remote system via the network.
+
+ The ::connect routine attempts to establish a connection to a
+ socket on the local or remote system using the specified address.
+ The
+ <a href="http://pubs.opengroup.org/onlinepubs/9699919799/functions/connect.html">POSIX</a>
+ documentation is available online.
+
+ There are three states associated with a connection:
+ <ul>
+ <li>Not connected</li>
+ <li>Connection in progress</li>
+ <li>Connected</li>
+ </ul>
+ In the "Not connected" state, calls to ::connect start the connection
+ processing and update the state to "Connection in progress". During
+ the "Connection in progress" state, connect polls for connection completion
+ and moves the state to "Connected" after the connection is established.
+ Note that these states are only visible when the file descriptor is marked
+ with O_NONBLOCK. Also, the POLL_WRITE bit is set when the connection
+ completes and may be used by poll or select as an indicator to call
+ connect again.
+
+ @param [in] s Socket file descriptor returned from ::socket.
+
+ @param [in] address Network address of the remote system
+
+ @param [in] address_len Length of the remote network address
+
+ @returns ::connect returns zero if successful and -1 when an error occurs.
+ In the case of an error, errno contains more details.
