Folks,
I have a question about how dbGetLink works. I have read the Application Developer's Guide (3.15.5) but it is not clear. Specifically I want to understand how it works under the following conditions:
- Link is an output link
- Link process type is CA
- The output PV resides in another IOC.
Does dbGetLink actually read the value from the other IOC? It seems like that would be a slow operation, and so would require the record to be asynchronous? Or does the database put a camonitor on that external record so the link value can be obtained without an actual caget operation? If so, I cannot find this mentioned in the Application Developer's Guide. It only describes channel access monitors being set up for input links, not output links.
Thanks,
Mark
