[openrtm-users 01201] Re: Howto check for data port buffer full error

[Geoffrey Biggs]

One possibility is using the OnOverflow callback on your port. When a
buffer overflow occurs, this callback should be called. You can register
a functor to this callback for the port in your component.

Aside from that, it's possible the status is not being propagated
correctly. The buffer is not held directly in the port object. It is
held in the connection between the two ports - think of it as the buffer
floating in the ether mystically. You could try exposing the connectors
and checking their status directly to see if it's being propagated properly.
