[openrtm-users 02811] Re: Checking connection before connecting two ports

[Ando Noriaki]

Hello,

You can know whether a port is identical by using
CORBA::Object::is_equivalent() method.

For example,

if (this_port.is_equivalent(that_port)) {
  // this_port is that_port
}

Best regards,
Noriaki Ando
