[Net->Connect] is used to establish an outgoing TCP connection with a remote host on a specific port. Once a connection is established data can be read from the connection using [Net->Read] or written to the connection using [Net->Write].

[Net->Connect] returns [Net_ConnectOK] if the connection was made successfully or [Net_ConnectInProgress] if the object already has an open connection.


Variable: 'Connection' = (Net);
$Connection->(Connect: '', 80);
Variable: 'Data' = $Connection->(Read: 32768);


Required Parameters
Host Name The DNS host name or IP address of the remote host.
Port The port number to connect to.


To connect to a remote server using TCP:

Use the [Net] type and its member tags to establish a TCP connection. The following example opens a blocking TCP connection to the Web server running on an example server and fetches the root document. The result will be an HTML page.

[Variable: 'myConnection' = (Net)]
[$myConnection->(SetBlocking: True)]
[Var: 'Result' = $myConnection->(Connect: '', 80)]
[Fail_If: $Result != Net_ConnectOK, (-1), 'TCP Error']
[Variable: 'Result' = $myConnection->(Write: 'GET / HTTP/1.0\r\n\r\n')]
[Variable: 'Output' = $myConnection->(Read: 32768)]
[Output: $Output]
