Close a Socket Connection

See more Socket/SSL/TLS Examples

Demonstrates Socket.Close, which gracefully terminates and closes the current TCP, TLS, or SSH channel connection. The argument bounds how long to wait for clean shutdown processing.

var
success: Boolean;
socket: HCkSocket;
bTls: Boolean;
maxWaitMs: Integer;

begin
success := False;

socket := CkSocket_Create();

//  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 := CkSocket_Connect(socket,'example.com',5000,bTls,maxWaitMs);
if (success = False) then
  begin
    Memo1.Lines.Add(CkSocket__lastErrorText(socket));
    Exit;
  end;

//  StringCharset controls the character encoding used when sending and receiving text.
CkSocket_putStringCharset(socket,'utf-8');

//  Gracefully close the current TCP, TLS, or SSH channel connection.  The argument is the maximum
//  number of milliseconds to wait for clean shutdown processing (0 waits indefinitely).
success := CkSocket_Close(socket,1000);
if (success = False) then
  begin
    Memo1.Lines.Add(CkSocket__lastErrorText(socket));
    Exit;
  end;
Memo1.Lines.Add('Connection closed.');

CkSocket_Dispose(socket);
