<p>Used to connect as a client to a TCP or TLS socket via the network card. This can be local or remote, if local, it is recommended that you use the Unix Socket Implementaion of <code>connectTo</code> instead as it is much faster since it avoids the network card alltogether.</p>
|
||||
|
||||
<ol>
|
||||
<li>
|
||||
<code>id</code> <strong><em>required</em></strong> is the string id of the socket being connected to. For TCP & TLS sockets, this id is added to the <code>ipc.of</code> object when the socket is created with a refrence to the socket.</li>
|
||||
<li>
|
||||
<code>host</code> <strong><em>optional</em></strong> is the host on which the TCP or TLS socket resides. This will default to <code>ipc.config.networkHost</code> if not specified.</li>
|
||||
<li>
|
||||
<code>port</code> <strong><em>optional</em></strong>
|
||||
</li>
|
||||
<li>
|
||||
<code>callback</code> <strong><em>optional</em></strong> this is the function to execute when the socket has been created.</li>
|
||||
</ol><p><strong>examples</strong> arguments can be ommitted solong as they are still in order.<br>
|
||||
So while the default is : (id,host,port,callback), the following examples will still work because they are still in order (id,port,callback) or (id,host,callback) or (id,port) etc.</p>
