[vtkusers] a bug of VTK4.0 ?

[Song Li]

Hi,
 I am quite confused with these lines in
vtkSocketCommunicator::WaitForConnection(int port) in VTK4.0:

 if ( bind(sock, (sockaddr *)&server, sizeof(server)) )
    {
    vtkErrorMacro("Can not bind socket to port " << port);
    return 0;
    }

As I know "bind" returns -1 when there is error, so why it isn't look
like " if ( bind(sock, (sockaddr *)&server, sizeof(server)) < 0 )" ? A
bug??
