Subject: CA library usage problem

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
