Receive a Bounded String from a Socket

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveStringMaxN, which receives and decodes text like ReceiveString but reads at most a given number of input bytes.

success = false

socket = Chilkat::CkSocket.new()

#  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.
bTls = true
maxWaitMs = 5000
success = socket.Connect("example.com",5000,bTls,maxWaitMs)
if (success == false)
    print socket.lastErrorText() + "\n";
    exit
end

#  StringCharset controls the character encoding used when sending and receiving text.
socket.put_StringCharset("utf-8")
#  Send a request using a simple application-defined text protocol in which each message ends with a
#  CRLF.

if (success == false)
    print socket.lastErrorText() + "\n";

#  Receive and decode text like ReceiveString, but read at most the given number of input bytes.
#  The limit is measured in bytes, not Unicode characters.
