Connect a TCP or TLS Socket

See more Socket/SSL/TLS Examples

Demonstrates Socket.Connect, which establishes a TCP connection to a host and port. Setting the TLS argument to _TRUE_ performs a TLS handshake after the TCP connection succeeds.

load ./chilkat.dll

set success 0

set socket [new_CkSocket]

#  Connect to the server using TLS.  The 3rd argument enables the TLS handshake after the TCP
#  connection succeeds; the 4th is the maximum time to wait, in milliseconds.
set bTls 1
set maxWaitMs 5000
set success [CkSocket_Connect $socket "example.com" 5000 $bTls $maxWaitMs]
if {$success == 0} then {
    puts [CkSocket_lastErrorText $socket]
    delete_CkSocket $socket
    exit
}

#  StringCharset controls the character encoding used when sending and receiving text.
CkSocket_put_StringCharset $socket "utf-8"

#  The socket is now connected and ready to send and receive data using whatever protocol the
#  application implements.
puts "Connected: [CkSocket_get_IsConnected $socket]"

#  Close the connection when finished.  The argument is the maximum time to wait for a clean
#  shutdown, in milliseconds.
set success [CkSocket_Close $socket 1000]
if {$success == 0} then {
    puts [CkSocket_lastErrorText $socket]
    delete_CkSocket $socket
    exit
}
