+/**
+ Establish the known port to listen for network connections.
+
+ The ::listen routine places the port into a state that enables connection
+ attempts. Connections are placed into FIFO order in a queue to be serviced
+ by the application. The application calls the ::accept routine to remove
+ the next connection from the queue and get the associated socket. The
+ <a href="http://pubs.opengroup.org/onlinepubs/9699919799/functions/listen.html">POSIX</a>
+ documentation for the bind routine is available online for reference.
+
+ @param [in] s Socket file descriptor returned from ::socket.
+
+ @param [in] backlog backlog specifies the maximum FIFO depth for the connections
+ waiting for the application to call accept. Connection attempts
+ received while the queue is full are refused.
+
+ @returns The listen routine returns zero (0) if successful and -1 upon failure.
