Receive a 16-bit Integer from a Socket

See more Socket/SSL/TLS Examples

Demonstrates Socket.ReceiveInt16, which reads exactly two bytes as a 16-bit integer and stores the result in the ReceivedInt property. Byte order and signedness are selectable.

var
success: Boolean;
socket: HCkSocket;
bTls: Boolean;
maxWaitMs: Integer;
bBigEndian: Boolean;
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 two bytes as a 16-bit integer and store the result in the ReceivedInt property.
//  The 1st argument selects byte order (1 = big-endian); the 2nd selects unsigned interpretation.
bBigEndian := True;
bUnsigned := False;
success := CkSocket_ReceiveInt16(socket,bBigEndian,bUnsigned);
if (success = False) then
  begin
    Memo1.Lines.Add(CkSocket__lastErrorText(socket));
    Exit;
  end;
Memo1.Lines.Add('Received 16-bit integer: ' + IntToStr(CkSocket_getReceivedInt(socket)));

CkSocket_Dispose(socket);
