Experimental Physics and Industrial Control System
Good morning All,
Any of you use dbLoadRecords( char * dbfile, char *
substitutions) or dbLoadTemplate().
It's fine but I have another question :) Both functions read
file. I wouldn't catch your attention why I need something because it is
another area of distributed control system. Let say - I need function
dbLoadRecordsNew( char * records, char * substitutions), where
records is usual db file.
I looked into code and was very unhappy. dbLoadRecords comes to
dbReadDatabase( ... char * filename ...). That was written so far ... on
yacc (???). Basically, code hasn't comments and isn't self-documented.
Application Development doesn't give information too. I couldn't find
function like dbLoadRecordsNew. Is it correct?
I thought a little and decided that way to write simple
dbLoadSingleRecord( char * record) function can be easier (then
understand dbReadDatabase() )
I suppose that should be like
1. There is global variable DBBASE *pdbase that is root Epics DB.
(Manual writes that IOC can have some DBs ... = some pdbase. Is it
correct?)
So first is allocation DB root dbAllocBase()
2. Each record has entry in pdbase.
Call DBENTRY * dbAllocEntry(DBBASE *pdbase). That allocates memory for
entry (!= for record) (?) and link into root.
3. Allocate memory for record. Call malloc with according record?
4. Fill record structure
...
And IOCInit()
Has anybody knowledge? Can he help me a little?
Thanks, Andrei.
