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

listenSocket = chilkat2.Socket()

# Pass a value of 0 for the port number to randomly select
# an unused port.
# (The 2nd argument allows for a backlog of 25 pending connection requests when accepting connections.)
success = listenSocket.BindAndListen(5555,25)
if (success != True):
    print(listenSocket.LastErrorText)
    sys.exit()

# Find out what port was chosen.
# Note: The ListenPort propety was added in Chilkat v9.5.0.59
listenPort = listenSocket.ListenPort
print("Chosen listen port = " + str(listenPort))
