Experimental Physics and Industrial Control System
I've just discovered that calling ca_context_create(1) after iocInit() appears to succeed (it returns ECA_NORMAL) ... but the resulting context is not very healthy! In my particular case I find that ca_array_get_callback delivers zero length data, but I expect other deeper problems are to be found.
I understand that I need to call ca_context_create() a good deal earlier, but I don't really understand why it appears to succeed -- is it possible for an error code to be returned instead, please? (In some future version of EPICS, I'm testing this on 3.14.11.)
Alternatively, is there some reliable way I can test whether it has succeeded? I don't have full control over when my library is initialised, so detecting an error immediately would be more friendly to the user.
