64<h2>Description</h2>
65    <div class="section">
66<p>Uses the specified socket descriptor to attempt to connect to the specified remote host.</p><p>If no local address has been bound to the socket using the <a href="../../nn/socket/Bind.html"><CODE>Bind</CODE></a> function, then <a href="../../nn/socket/Connect.html"><CODE>Connect</CODE></a> binds an unused local address to the socket. For a stream socket (<CODE>SO_SOCK_STREAM</CODE>), this function usually blocks until a connection is established but it will return as soon as possible if non-blocking mode has been set by the <a href="../../nn/socket/Fcntl.html"><CODE>Fcntl</CODE></a> function. In such cases, use the <a href="../../nn/socket/Poll.html"><CODE>Poll</CODE></a> function to check whether a connection has been established. If the connection attempt failed, the <CODE>Poll</CODE> return value has its <CODE>POLLRDNORM</CODE> and <CODE>POLLWRNORM</CODE> bits set to <CODE>1</CODE>. You can also detect connection failures via the errors returned by functions that you later call to send or receive data. For a datagram socket (<CODE>SOCK_DGRAM</CODE>), this function has the same behavior in both blocking and non-blocking mode because it simply changes the socket address to which datagrams are sent.</p><!-- write here --></div>
