Receive a 32-bit Integer from a Socket

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveInt32, which reads exactly four bytes as a signed 32-bit integer and stores the result in the ReceivedInt property. Byte order is selectable.

var
success: Integer;
socket: TChilkatSocket;
bTls: Integer;
maxWaitMs: Integer;
bBigEndian: Integer;

begin
success := 0;

socket := TChilkatSocket.Create(Self);

//  Connect to the server using TLS.
bTls := 1;
maxWaitMs := 5000;
success := socket.Connect('example.com',5000,bTls,maxWaitMs);
if (success = 0) then
  begin
    Memo1.Lines.Add(socket.LastErrorText);
    Exit;
  end;

//  Read exactly four bytes as a signed 32-bit integer and store the result in the ReceivedInt
//  property.  The argument selects byte order (1 = big-endian, network byte order).
bBigEndian := 1;
success := socket.ReceiveInt32(bBigEndian);
if (success = 0) then
  begin
    Memo1.Lines.Add(socket.LastErrorText);
    Exit;
  end;
Memo1.Lines.Add('Received 32-bit integer: ' + IntToStr(socket.ReceivedInt));
