CA wishlist :)

[Heinrich du Toit <heinrichdt@tlabs.ac.za>]

Hi

Wouldn't it be nice to specify the EPICS_CA_* values firstly through 
functions in the library rather than environment variables only.
And then secondly on a per-connection basis.
So you can have seperate setup for every PV connection. ?


Is it possible to link casw into a program somehow? So that your client 
program can monitor the status of a specific IOC?


It would be nice if the ARRAY_SIZE_LIMIT thing be done differently? 
Maybe removed all-together? Or be implemented in a way that it can be 
easily changed on the fly inside a program - The documentation aint very 
clear if this env-var is read while the program is running or only on 
startup?


Then a question:
Can somebody explain the relationship between.
ca_flush_io
ca_poll
ca_pend_io
ca_pend_event
And which ones of these I don't have to call in a enabled pre-emptive 
callback environment?

And lastly - with the CA library.
How do I control users - password ect in case of Access Control on IOC's ?

Thanks you for your answers in advance :)
