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: Boolean;
socket: HCkSocket;
bTls: Boolean;
maxWaitMs: Integer;
bUnsigned: Boolean;

begin
success := False;

socket := CkSocket_Create();

//  Connect to the server using TLS.
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;

//  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 := True;
success := CkSocket_ReceiveByte(socket,bUnsigned);
if (success = False) then
  begin
    Memo1.Lines.Add(CkSocket__lastErrorText(socket));
    Exit;
  end;
Memo1.Lines.Add('Received byte value: ' + IntToStr(CkSocket_getReceivedInt(socket)));

CkSocket_Dispose(socket);
