- * Function: listen
- *
- * Description:
- *   To accept connections, a socket is first created with socket(), a
- *   willingness to accept incoming connections and a queue limit for incoming
- *   connections are specified with listen(), and then the connections are
- *   accepted with accept(). The listen() call applies only to sockets of
- *   type SOCK_STREAM or SOCK_SEQPACKET.
- *
- * Parameters:
- *   sockfd   Socket descriptor of the bound socket
- *   backlog  The maximum length the queue of pending connections may grow.
- *            If a connection request arrives with the queue full, the client
- *            may receive an error with an indication of ECONNREFUSED or,
- *            if the underlying protocol supports retransmission, the request
- *            may be ignored so that retries succeed.
- *
- * Returned Value:
- *   On success, zero is returned. On error, -1 is returned, and errno is set
- *   appropriately.
- *
- *   EADDRINUSE
- *     Another socket is already listening on the same port.
- *   EBADF
- *     The argument 'sockfd' is not a valid descriptor.
- *   ENOTSOCK
- *     The argument 'sockfd' is not a socket.
- *   EOPNOTSUPP
- *     The socket is not of a type that supports the listen operation.
- *
- * Assumptions:
