​
Function Syntax

long TcpClose( dword socket);

As soon as the socket has been successfully closed, an OnTcpClose event is initiated once on the remote station.

​
Parameters

  • socket: The socket to be closed.

​
Return Values

  • 0: The function completed successfully.
  • WSA_INVALID_PARAMETER (87): The specified socket was invalid.
  • SOCKET_ERROR (-1): The function failed. Call IpGetLastError to get a more specific error code.

void disconnectSocket( dword socket )
{
  if (socket != -1)
  {
    TcpClose(socket);
  }
