Hi all, i guess I have a misunderstanding how to use the user callback functions together with a subscription to a PV variable. In my userfunc the value of arg.status is always 1 which evaluates to a ca_message of "Normal successful completion". But the documentation say's to check against ECA_NORMAL witch is 0. What am I doing wrong here. Regards Jörn
