# This example requires the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

socket = Chilkat::CkSocket.new()

# Connect to port 5555 of localhost.
# The string "localhost" is for testing on a single computer.
# It would typically be replaced with an IP hostname, such
# as "www.chilkatsoft.com".
ssl = false
maxWaitMillisec = 20000
success = socket.Connect("localhost",5555,ssl,maxWaitMillisec)
if (success != true)
    print socket.lastErrorText() + "\n";
    exit
end

# Set maximum timeouts for reading an writing (in millisec)
socket.put_MaxReadIdleMs(10000)
socket.put_MaxSendIdleMs(10000)

# Pretend, for the sake of the example, that the
# ficticious server is going to send a "Hello World!" 
# after accepting the connection.  
# Note: Technically, the ReceiveString may not receive the
# complete string, although it's highly probable given the short
# length of the "Hello World!" message. 
# See this Chilkat blog post for more information:
# http://www.cknotes.com/?p=302
receivedMsg = socket.receiveString()
if (socket.get_LastMethodSuccess() != true)
    print socket.lastErrorText() + "\n";
    exit
end

# Close the connection with the server
# Wait a max of 20 seconds (20000 millsec)
success = socket.Close(20000)

print receivedMsg + "\n";
