Hello,

I would like to print the field name that is in the DOL.
What are all the fields for the structure pao->dol?
pao->dol.type --- ok

I could not find this information in the header file.
My understanding is that the epics database DOL are DBF_INLINK.
Where is the associated structure?

See link.h for the different structure definitions. pao->dol is a struct link which is typedef'd to DBLINK. You should check dol.type which for a DOL field at runtime should only ever be CONSTANT, DB_LINK or CA_LINK, and use the appropriate member in the union value to get the field value - you'll only need to use the constantStr or pv_link members. If you want to see some code that does this, look at the function dbGetString() in base/src/dbStatic/dbStaticLib.c.
