Description

Receives data from a TCP connection associated with the index iTCPClient in the TCP client resource manager. The resulting string is returned in s. The read timeout is set to 1000ms, if no data is received before then, s will return an empty string. If s is not empty, the function will return true.

Example

var
  i: Integer;
  Nick, s: string;
  Running: Boolean;

begin
  Running := True;
  Nick := 'Test' + IntToStr(Random(999));
  i := TCPConnect('irc.scar-divi.com', 6667, 1000);
  try
    TCPSend(i, 'NICK ' + Nick);
    TCPSend(i, 'USER ' + Nick + ' 0 * :' + Nick);
    TCPSend(i, 'JOIN #scar');
    while Running do
    begin
      TCPReceive(i, s);
      if s = '' then
        Wait(500)
      else
        WriteLn(s);
      if Pos('= #scar', s) > 0 then
      begin
        TCPSend(i, 'PRIVMSG #scar :Hello World!');
        Running := False;
      end;
    end;
  finally
    TCPFree(i);
  end;
end.
