Receive a Single Byte from a Socket

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveByte, which reads exactly one byte and stores its numeric value in the ReceivedInt property. The argument selects signed or unsigned interpretation.

var
success: Integer;
socket: TChilkatSocket;
bTls: Integer;
maxWaitMs: Integer;
bUnsigned: 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 one byte.  Its numeric value is stored in the ReceivedInt property.  Passing 1
//  interprets the byte as unsigned (0 through 255); 0 interprets it as signed.
bUnsigned := 1;
success := socket.ReceiveByte(bUnsigned);
if (success = 0) then
  begin
    Memo1.Lines.Add(socket.LastErrorText);
    Exit;
  end;
Memo1.Lines.Add('Received byte value: ' + IntToStr(socket.ReceivedInt));
