[openrtm-users 01202] Re: Howto check for data port buffer full error

[Steffen Wittmeier]

Hi,

I was looking for the onOverflow callback method as I know it from 
OpenRTM 0.42 but I could not find it in version 1.0. Did it move to some 
other class?

Maybe I will try the 2nd option using the connectors in the meantime.
